Peterson has played very well so far this season. He made what was arguably the best defensive play of the season last week in a one-handed interception running out of bounds against the Bills.
He won’t get every call but he plays with authority. The Cardinals rely on him as a leader on defense. We saw a lot of that last season too.
After a victory last season, Arians gave the team Monday off in what he calls Victory Monday. The defense on that Sunday however had played so terribly, he told the defense no Monday off and to be at team headquarters to start the business of making things right on that side of the ball.
That is the type of leadership the Cardinals need for the younger guys. Last week Arians pointed out that there were a lot of young followers who weren’t following very well. A leader needs to have followers. Everyone needs to be on the same page. Peterson is someone that can handle that chore.
