4 Vikings falling down the depth chart after Week 1 of the preseason

Camryn Bynum – S

The Broncos’ first trip to the end zone last Saturday was the result of an 80-yard bomb from quarterback Drew Lock to receiver KJ Hamler.

Vikings cornerback Cameron Dantzler was seen trailing Hamler on the play and some might point the finger at the Minnesota defender for giving up the big score. But the guy who deserves the most blame for the long-distance touchdown is rookie safety Camryn Bynum.

Bynum bit on the play-action handoff by Lock and by the time the young Vikings safety realized that Hamler was blazing down the field behind him, it was too late.

If there is one thing that Mike Zimmer emphasizes to his defensive backs, it’s to keep your guy in front of you. Zimmer isn’t going to freak out if an opposing offensive player is able to make a catch, as long as it’s not made behind the secondary.

Bynum is in the middle of making a position switch from corner to safety, so his inexperience has to be taken into account. But breaking arguably the No. 1 rule of Zimmer’s pass defense philosophy isn’t going to help his chances to make Minnesota’s regular-season roster.
