What the heck is a "rebuild mode'? Did they bring it Haasan Reddick, Daquan Jones, Morgan Fox to help rebuild? Hopefully the Panthers organization are trying to win games, especially sitting at 3-0 and leading the division through the 1st quarter of the season. If Sherman can help the defense in light of Horn's injury sign him.
McDermott knew Rivera's philosophy defensively. If and I mean big IF, Rivera has the players on his defense he might have a top 5 defense. McDermott knows how to dismantle Rivera's defense.
I like Rivera a lot but his defense is not build to beat highly potent offenses. Very clear to me.
