The Packers are bent over 12 million ways by Favre at the moment, I don't know what version of this you're looking at.
If he is adamant about suiting up, the Packers either pay him 12 million dollars, try to trade him and see if another team would pay him 12 million dollars this year, or just straight up release him and risk him going to a team in the division.
If they decide to keep him, no way is 12 million going to sit on the bench playing backup, he starts, period. Experiment with Rodgers, a fork stuck so deep in the done with the Packers new guy, his toes ache. Packers look like idiots too boot. Favre wins.
If they try to trade him, very few teams would take on that 12 million for a QB his age, the Great Brett Favre or not. Not too mention Favre could refuse any trade the Packers try to make. Favre still has all the power.
Or the third and last option, the Packers release him and he gets to chose wherever he wants to go, to whomever will have him. And in a clean-sweep, Favre takes it all and the Packers are left with only the itch he left them.
Packers 0
Favre 3
And the great thing, he's just getting started. Whatever they did to piss him off, I just hope it chokes them real good going down. I know I'm enjoying every moment of this Cowboy Fan giving it to the Green Bay Packers on a Grand Scale. You go Brett!
