Spagnuolo was a hot prospect before the season, and this season is cementing his status as a top 3 defensive coordinator (I think he's the best) in the game. Truly legit head coaching prospect, his stock actually improved since winning the Super Bowl. Strahan is gone, and Osi is gone, and yet the Giants are still as disruptive as ever on D.
I believe that Josh McDaniels' stock has been helped more with Brady's injury than if Brady was healthy throwing 45 TDs. McDaniels has managed to turn a career backup QB (hasn't started since high school) into a legitimate threat by building schemes on his talents. The true measure of a person is his performance under adversity, and NE's offense has been solid even without Brady, Maroney, Morris, and Jordan.
