Reports out of DC point to Shanny NOT wanting to make the trade for RGIII and basically being told to play him this year and not Cousins. He does not have the final say in DC that you all seem to think he does.
Biggest problem is RGIII lack of maturity. He was the one that forced the issue last year in the playoffs, then lets his Dad blast the coach all offseason for playing him. So if Elway was hobbled in the playoffs and trying to gut out a win (in a close game that Was was controlling) you would be fine with the backup who got no reps coming in? Really, so if Manning is struggling in the playoffs bring in Brosweiler even though the game is close? As a coach your hand is kind of forced.
Zorn left that place in a mess. Shanny has put it back together a bit, but they were always in for a tough year this year.
