Here's another perspective.
Snyder has buddyed up to RGIII much the way he did with Portis. He and his wife had Thanksgiving dinner in Dallas with RGIII and his fiancee the day after the win while RGIII was waiting to cheer on Baylor that Saturday. I think this is kind of weird and it clearly shows favoritism by Snyder towards his "star player". I don't like it at all...Snyder should be AWAY from the team except to sign the paychecks, celebrating the holiday with his family or people his own age, and certainly not appearing to play favorites like he is.
While RGIII isn't a whiner like Portis, Shanahan sees that Snyder has taken him "under his wing" so to speak. He knows what happened to Zorn after Portis began complaining to Snyder about how things were being run.
This makes me wonder...I'm sure Shanahan could have pulled RGIII out for Cousins, and all would be forgiven IF we win the game and advance. But if we don't, you have RGIII saying that he felt like he could have played to the media, that he wants to play. You have a seething Snyder blaming Shanahan for taking out his star QB when he wanted to play as well.
Have to wonder if this was part of Shanahan's reluctance to do anything until it was too late.
