Reports are that E.J. is healthy enough right now to fully participate once camp opens.  But we’ll have to see how the Vikings decide to play that.  They could elect to place Henderson on the PUP list, and bring him along slowly.

As I indicated before, when healthy, Henderson has shown elite skills, especially as a run-stopper and up-the-middle pass rusher.  But, the last two years, Henderson’s march to the Pro Bowl was cut short.  In 2008, surgery on his left foot ended his year after only four games.  And in ’09, as we all vividly remember, he suffered a gruesome leg break against Arizona, and was forced to watch the Vikings’ playoff run from the sidelines.

The man who replaced Henderson last season, Jasper Brinkley, comes into camp as a rising talent.  We’re looking for further improvement from Brinkley, who becomes an important player when you consider E.J.’s history of not being able to finish seasons.

As far as the outside spots go, Ben Leber and Chad Greenway are as locked-in as you can get.  Rookie Nate Triplett will vie with Kenny Onatolu, J Leman and Erin Henderson to win back-up/special teams roles.

Heath Farwell returns as one of the league’s most fearsome crazy man-crushing special teams bastards.

On the defensive side, the big pick was DE Everson Griffen, a large talent whose commitment often came into question in college.

Griffen has the potential to be a starter some day, especially if the Vikes and Ray Edwards end up parting ways. But he also has the potential to be an even bigger headache than Edwards.

Linebacker was the other position the Vikes addressed heavily on day 3, taking Gopher Nate Triplett and Ryan D’Imperio of Rutgers. Neither figures to be much in the mix this year, but with Ben Leber coming to the end of his contract, who knows what either of them might be down the road.

Offensively, the Vikes addressed the lack of offensive line depth by drafting Wake Forest guard Chris DeGeare.

They also added to their receiver corps by taking UAB’s Joe Webb, who played quarterback in college, but will not be getting any action behind center in Minnesota.

Rounding out the picks was tight end Mickey Shuler of Penn State. Again, don’t expect to see much from this guy in the near-term.

Like I said, Griffen is the guy to keep an eye on as a potential starter. The rest of these fellows? They fill out the training camp roster nicely and some may even make the practice squad.
