I feel like weighing in on a 7/13 thread...
There is a common presumption that if #7 does not start, or is benched after starting, that he is done. (psychologically ruined, confidence destroyed etc) I disagree with this assumption. It is possible, but it is far from certain. Imagine #13 missing time later in the season due to injury, a young QB with 20 starts under his belt could come back in and lead the team. It is possible. Notice I am not saying who I think should start, I just don't believe it's a given that #7 is too fragile to recover from this scenario. I also think the coaches know a lot more than I do. (just not nearly as much as some other fans)
Finally. A good point that has been much ignored.
Rich Gannon persevered through many benchings and coaches and many other QBs did so as well.
