As the Vikings bask in the glow of their 26-23 overtime win against the Jacksonville Jaguars on Sunday, one word comes to mind to describe their defensive performance: rollercoaster.

It seemed that for every diving pass deflection there was blown coverage, for every backfield tackle there was a Viking falling backwards after getting blasted by a running back. The Jaguars were able to move the ball pretty well, thanks in part to an atrocious Vikings third-down defense. However, the defense held strong when it counted, keeping Jacksonville to 9 points through the first half. The following is a breakdown of the secondary, linebackers, and defensive front of the undefeated Minnesota Vikings.

Secondary

Any discussion about the Vikings defensive performance on Sunday will begin and end with that fateful 39-yard touchdown pass by Blaine Gabbert with 20 seconds left. Chris Cook’s blown coverage gave Vikings Nation flashbacks to last season and the lost second half leads that plagued the team early in the year. That play notwithstanding, the secondary’s performance overall wasn’t that bad. First round draft pick Justin Blackmon was kept to just 24 yards, and no receiver had more than 75 yards thanks to solid play from the cornerbacks.

Safeties Harrison Smith and Mistral Raymond also struggled with the same up and down play as the rest of the defense. While Raymond had a nice pass breakup on a deep pass early in the 4th quarter, he was also responsible for the blown coverage on TE Mercedes Lewis that resulted in an easy touchdown for Jacksonville.

Linebackers

The linebackers for Minnesota also flashed a few times during this game, especially with Chad Greenway’s multiple pass breakups. However, the group still struggled to maintain consistent pass coverage, which was a big factor in the poor third down defense. That issue aside, Greenway, Erin Henderson, and Jasper Brinkley were the top three tacklers in the game and came up big during the goal line stand in the first half.

Defensive line

The star of the defensive line for the Vikings was without a doubt Brian Robison. While the defensive end was only credited with 3 tackles, all three of those tackles were impact plays. During the Jaguars’ opening drive, Robison dove and brought down Rashad Jennings, preventing the backup running back from hitting the wide open patch of green in front of him. If Robison doesn’t make that tackle, there’s a great chance Jennings gets a first down, if not a touchdown. Robison’s other two tackles were for 1 and -1 yard gains, and that doesn’t include his pass deflection and multiple quarterback

The rest of the defensive line held up okay, holding the Jags to just over 100 yards rushing. On top of that, the unit also forced the lone turnover for the Vikings, a Blaine Gabbert fumble recovered by Kevin Williams. Surprisingly, Jared Allen was a complete non-factor, despite going up against a rookie left tackle Eugene Monroe. Luckily for Allen (and the rest of us), Robison had his fantastic game.

All in all, there were some flaws in the defense on Sunday, but there were also a lot of positives. Sure, I’d like to see more consistency throughout the game, but the fact is this defense held strong when it needed to and kept the game close enough for Chris Cook to almost give it away at the end.

As teams try to whittle their rosters down to 53 players, there are question marks for virtually every position on the Vikings.

However, there is one player in particular who has captivated many of the Minnesota faithful. Quarterback McLeod Bethel-Thompson became one of the preseason success stories with a couple of strong performances and a cannon of an arm. Fresh off his 193-yard showing against the Texans that ended in a near game-winning drive, fans and pundits have speculated if he had earned himself a roster spot.

And while most of the conversation has centered on whether Bethel-Thompson, Joe Webb, or Sage Rosenfels deserve to be one of the two passers behind Christian Ponder, two factors are not being considered as heavily as they should. First, it’s important to note that the Vikings have the third spot on the waiver claim list, meaning there are only two teams (the Indianapolis Colts and the St. Louis Rams) who could claim Bethel-Thompson before Minnesota if he were to be released today.

This leads us to the second factor, which is whether or not those two teams ahead of the Vikings might draft the young passer with the rocket arm. Here’s a breakdown of where those two teams stand with their quarterback situations:

Indianapolis Colts

On roster: Andrew Luck, Drew Stanton, Chandler Harnish

The Colts are pretty set at quarterback, starting with first overall pick Andrew Luck. Luck has looked every bit the part of top draft pick and successor to Peyton Manning. Behind him, the Colts have a competition brewing between two solid quarterback options. Former Lions backup Drew Stanton is competing with Chandler Harnish, who finished the preseason against the Bengals with a 112.0 passer rating. There is little to no chance the Colts would use up a practice squad spot on Bethel-Thompson.

St. Louis Rams

On roster: Sam Bradford, Kellen Clemens, Austin Davis

There’s no question about who the starting and backup quarterbacks are for the Rams. Sam Bradford has a history of injuries, but finished the preseason strong with three touchdowns in a quarter and a half. Kellen Clemens hasn’t necessarily blown anyone away with his numbers, but is the clear backup to Bradford. Rookie Austin Davis is on the bubble, but could make it on to the 53-man roster. And although St. Louis is more likely than Indianapolis to claim Bethel-Thompson should he be cut, the chance that they would make the move is slim.

Given the quarterback situations in both Indianapolis and St. Louis, the Vikings could cut Bethel-Thompson and still have a good shot at signing him to the practice squad tomorrow morning. Bethel-Thompson is the quintessential developmental quarterback, and the Vikings may very well designate him to that role.

In my years as a Vikings fan, I can’t remember a time quite like the beginning of last season. After strong performances in the first half of each of the initial three games, the team collapsed in epic fashion to start off 0-3. In those games, there were always one or two players from the opposition who came up big to save the day, and a player in purple who simply couldn’t keep up.

Every game has a key matchup to watch, and this season won’t be any different. That being said, here is a game-by-game breakdown of the most interesting matchup to watch during the first half of the 2012 season for the Vikings.

Week 1 – Home against Jacksonville Jaguars

DT Kevin Williams vs. RB Maurice Jones-Drew: As much as it pains me to say, the Jaguars are a very similar team to the Vikings. Both squads feature one-dimensional offenses led by second-year quarterbacks. Like the Vikings, that lackluster scoring group is led by a primetime running back. MJD is a power runner who loves to bowl people over and break through the interior of the defensive line. Kevin Williams, in a contract year and needing to prove himself useful as an aging veteran, will have to bounce back from a down year last season and stuff the run.

If Williams can step up, Jacksonville will have to rely on their passing game. This should be an easy first test for the rebuilt Minnesota secondary. Despite drafting the best rookie wideout Justin Blackmon, he still has the worst rookie quarterback from last year, Blaine Gabbert, throwing to him. Stopping MJD and the Jags’ run game is crucial if Minnesota wants to start the reason off on the right foot.

Week 2 – At Indianapolis Colts

LB Jasper Brinkley vs. QB Andrew Luck: Plenty of eyes will be on this game as the sports world watches Andrew Luck try and live up to the hype associated with a No. 1 overall pick. This is a pretty evenly-matched game, but one that should come down to one factor: Can the rejuvenated Colts offense pick apart a suspect Vikings defense? The answer to that question will depend on how Jasper Brinkley performs. As the middle linebacker, he’s essentially the quarterback of the defense and will be responsible for understanding and outperforming the quarterback of the offense in Andrew Luck.

Both players are unproven, especially Brinkley, who needs to shake off his injury-prone past and show enough potential to warrant his starting role. Brinkley will most likely have to deal with the other top draft pick from Indianapolis, being responsible for covering tight end Coby Fleener. At this point in the offseason, Brinkley is the biggest question mark on defense, but could alleviate some of those concerns with a strong performance against a rebuilding team.

Week 3 – Home against San Francisco 49ers

RG Fusco/Berger/Schwartz vs. DT Justin Smith: 49ers defensive tackle Justin had a breakout season last year, cementing his status as one of top rushing tackles in the league. This could be trouble for the Vikings and a restructured offensive line. While the tackles, center, and left guard positions seem to be locked in, the right guard position is much murkier. As training camp approaches, Brandon Fusco, Joe Berger, and Geoff Schwartz will battle for that last spot.

Smith is a beast up the middle, so it’s important for whoever wins the right guard spot to step up. The middle of the Vikings offensive line will have to hold up to keep Christian Ponder from spending most of the game on back.

Week 4 – At Detroit Lions

CB Chris Cook vs. WR Calvin Johnson: San Francisco in Week 3 may be the toughest test early in the season, but the Detroit Lions are the biggest test for the revamped secondary of the Vikings. A key part of this new look secondary is the returning Chris Cook, who will be spend most of the game covering Calvin Johnson. Minnesota needs to put a big-bodied CB on the big-bodied Megatron, and Cook fits that bill better than the other corners on the roster. Given how dynamic the Lions offense is, Cook is likely to see some man coverage throughout the game and will need to have a good showing against the elite wideout.

Week 5 – Home against Tennessee Titans

LB Chad Greenway vs. RB Chris Johnson: Luckily for me, I avoided Chris Johnson during last year’s fantasy football draft. Others, however, were less fortunate and watched in frustration as CJ2K put up mediocre numbers. Regardless, Johnson is a home run threat who will need to be kept in check. This is the perfect opportunity for Chad Greenway to prove his massive contract worthwhile. Greenway is a tackling machine and will need to be at his best against the Titans. The reason why Greenway should be the top tackler this game is Johnson’s running style. CJ2K likes to bounce around to the outside, and is extraordinarily good at avoiding the front four. Whether or not Johnson makes it past the second line of defense is what will determine the outcome of this game.

Week 6 – At Washington Redskins

DE Jared Allen vs. QB RGIII: The Vikings continue to make the rounds against young quarterbacks, with Washington being their fourth game featuring a first or second year signal caller. Typically, it would be up to the secondary to keep the QB in check, but the Redskins are a little different. While RGIII is a tremendous upgrade over Rex Grossman, the Redskins did practically nothing to fix a porous offensive line. This means Jared Allen should get through the protection easily and often. This is where things get interesting. Because Griffin looks to be one of the most athletic players in the entire league, Allen might have a hard time catching him to bring him down. Regardless of how many times we see Allen “roping the calf,” it should be an entertaining matchup to watch.

Week 7 – Home against Arizona Cardinals:

Special Teams Coordinator Mike Priefer vs. PR Patrick Peterson: Special Teams Coordinator Mike Priefer has done a good job of turning around a typically sub-par group despite losing what few leaders it had, like Heath Farwell. Usually, Priefer’s biggest responsibility is deciding what to do about Devin Hester twice a year. However, this could be his biggest test with Patrick Peterson establishing himself as the new top returner in the league right now. The battle for field position is always an important factor in winning games, and this game will hold true to that.

Week 8 – Home against Tampa Bay Bucs

DT Letroy Guion/Fred Evans vs. RB LaGarrette Blount/Doug Martin: Prior to Cleveland switching draft picks with the Vikings to get Trent Richardson, the Buccaneers were often thought of as the most common landing spot for the top-rated running back. LaGarrette Blount has shown flashes of promise the past couple seasons, but has tendency to make boneheaded moves on and off the field. While Tampa missed out on Richardson, they still drafted running back Doug Martin in the first round. This gives the Bucs a formidable 1-2 punch in the backfield.

The Vikings have struggled to stop the run consistently since Pat Williams left. That reinforced running game of the Bucs means the Minnesota defensive tackles will be tested heavily. All signs are pointing towards a rotation of Letroy Guion and Fred Evans next to Kevin Williams. Can this DT rotation hold up against the Tampa Bay running backs? The answer to that question may also decide who wins this game.

Check in a few days, when I dive into the interesting matchups for the second half of the Vikings regular season.
