Football is as much mental as it is physical.
Ted Thompson clearly made mistakes, but he could have also kept Favre and made him a backup too or he could have traded him to the Vikings or Buccaneers or start him as a Packer.
Any of those options other than being a Packer sound good? Not really.
Favre didn't decide what to do until the Summer. Clearly, Green Bay thought he was done. However, they should have been prepared.
Teams had to figure out whether they wanted Favre or not. Then a deal needed to be worked out. It's not as easy as just saying "let's get rid of Favre". The only team that probably would've taken him right away was the Vikings and you can't do that. You can't move a QB to a division rival. Same reason why Denver wasn't going to move Jay Cutler to one of their division rivals.
To state distractions doesn't effect players and that you should dump them because it does is absolutely absurd. Even TO has become a locker room distraction especially in Philly.
I'm not getting rid of say Donovan McNabb because he couldn't handle TO's ego.
Distractions are apart of the game, but you also have minor ones and big ones. A minor one shouldn't effect you. Unless you've been living under a rock on the moon, you should know that Favre was a huge distraction last year.
I'm certain Minnesota and Green Bay are going to be distracted in early October and early November this year. How can they not be? It will effect them, but again the outcome of the game will be determined largely due to the play on the field. Everything will contribute, but some more than others.
