Did you see Al Michael's interview with Brett Favre last night? I think it revealed a few things about why he came back another year. 1) Favre hesitated in making a decision to come back because he fears failure and he fears man. He said that he did not want to let people down either by playing or not playing another year. 2) Favre misses the camaraderie of being part of a team ... he said there's nothing like it! 3) Favre knows he will make a lot of money. No brainer.
Whatever the reason ... I'm glad he's playing another year for my favorite team -- the Vikes!
