BBAO: Peterson returns to Minnesota

We're Black and Blue All Over:

Minnesota Vikings running back Adrian Peterson joined the team's offseason program for the first time Monday, and coincidentally there was an NFL Network crew there to chronicle his arrival. And as it just so happens, the network managed to shoot video of Peterson carrying a 14-pound, sand-filled football during running back drills in a modified indoor organized team activity.

The rest of the Vikings' running backs were carrying the same ball, but the implication was that the drill was a response to Peterson's well-chronicled fumbling problems over the past few seasons. I've never seen the Vikings use that drill, but I haven't watched every offseason practice, either.

I think Peterson is the single biggest issue for the Vikings this week as they prepare for and later go through their veteran minicamp this weekend. We know their starting quarterback won't be in attendance. What we don't know is if Peterson has made any substantive changes to his style to limit the fumbles. He's spent the offseason working out on his own in Houston and has traditionally said he won't overreact to the issue. Whatever changes he is planning should be in evidence this weekend.
