Like I said earlier. Brett Farve isnt going to instantly make a team a contender. A team has to already have most of the pieces in place to be able to get it done, even with Farve. Most of the teams that have all of those pieces already together are pretty set with QBs. About the only team that would have an "opening" is Arizona. It doesnt look likely at al,l with them drafting Matt Leinart, that they would be willing to bring in another older QB to put in front of him. Even with Farve being light years better than Warner I dont see it.
What I see happening is that after this season or even next if he gets close enough to Marino's TD record, that Brett will walk off on his own terms. He already has a ring, sand 3 MVP awards so its not as if he's making a last ditch effort to cement his place in the game's history.
There's no reason for him to be a Johnny U. or Joe Namath and hang on just to hang on. Both of those guys were well past their primes when they finally decided to give it up. Im not even a Packer fan and I think it would be odd and also sad to see Brett Farve not playing in a Packer's uniform. Just as odd as it was to see Johnny U. in a Chargers' uniform, Joe Namath in a Rams', or Joe Montana in a Chiefs'.
