Teams in general have been playing more physical against the C's and also against IT. This is going to work with reffing crews that do not call a close game, a closely called game will put IT at the line more and force the other team to play a different level of D.
Isaiah is tired, he isn't getting calls and he seems more predictable lately--probably all symptoms playing off of each other.
I think word is out to play the C's physically--The coaches need to figure out how to stand up to this constant reaching and hacking D that teams are now employing against us.
