Not picking on you, Bob, as many others have made this very same comment but I just don't understand why this is such a widely held belief. Gray is a Senior more than halfway through his final season. Just about every offensive coach that he has played under, it seems, has come to the sobering realization that he's not a very good QB.
Today he played a good chunk of the game at WR. Makes it hard for me to believe he's not healthy enough to play QB. This staff wants to win games, needs to win games. If Shortell doesn't ding his head against NU, it's very possible Gray never takes any snaps at QB in that game either. So maybe it's not all that "obvious" that Gray gives them the best chance to win, unless the staff are a group of masochists who had every intention of losing the last couple games.
Let's face it, if you're healthy enough to take the field, and you've been replaced in a rivalry game by a kid who has never taken a college snap, it's hard for me to believe the staff has much confidence in you. He was clearly healthy enough to play last week against NU, and yet Shortell started that game. These aren't exactly ringing endorsements from the people who see you day in, day out.
Not looking to get into an argument, it's just that the actions/decisions of the staff would lead a reasonable person to believe there's just not a lot of faith there.
