There's not a lot in here I disagree with. However, the situation Favre has created has two real dimensions to it. First, no matter what, the Pack has egg on it's face. Second, the ONLY truly positive outcome to this season now, Favre or Rodgers, is a Super Bowl Championship.
No matter what happens short of a Super Bowl Championship, everybody and everything will be second guessed. Like it or not, and I don't, this distraction is going to last for years and is going to make Rodgers job of replacing Favre that much more difficult. He may never be embraced by the GB fans no matter how well he does after this circus unless he wins the big one.
Lastly, I don't think Favre can win the Super Bowl. In almost any scenario, he's going to have to go through cold weather games to do it, and he showed us over the last several years that he can't do that anymore.
Will Rodgers win the Super Bowl this year? I highly doubt it. Can he get us to the playoffs? Very possible. IMO, that's all Favre is going to be able to do too. Maybe win a couple more games along the way, but not the big one.
Which is why I'd put Favre on the bench and not play him. If Rodgers gets hurt, we've got a pretty good backup.
