He was probably one of the top five qbs last year, but he started the year with an injury, his offensive weapons don't seem as crisp, and his o-line is dramatically worse. When you ask him to be part of Peterson's offense, he's good. When you ask him to be the peyton manning of the vikes, he just can't do it. I wouldn't ever ask a future hall of famer to retire, but he is beginning to be to football what shaq is to basketball, imo.
