I think the Herm Edwards quote applies here. If you are trying to win the game, you need to do what it takes to win. If Will Grier gives us a better chance to win, then we need to play him. If he doesn't, then he should continue to sit. My big concern with putting him in the game is really less about him losing his confidence but if he is a marked improvement over Allen in taking care of the ball. I would say trust the coaches decision making on this however we all know that is a suspect notion.
