I don't think he's a loser as a person. I don't think he has what it takes to be an NFL starting or back up QB. He's too injury prone, as well as other issues. He did well in college if memory is correct, but many who did well in college don't do well in the NFL, for one reason or another. Sometimes I think it's they can't make the emotional adjustment between playing for the NCAA & NFL.
I most definitely believe we need a more reliable back up QB.
