I think saying "stick a fork in him, he's done" was the wrong way to word it.
Do i think he's no good? Nope. I still think he has "it".
Do i think he should come back and play here? Nope.
He stated he was done, and retired. That put the whole process into motion that we now will have Rodgers as our QB, good or bad.
It wouldn't be fair to Rodgers, OR the Packers to now change it all.
Don't get me wrong, I LOVE Brett Favre, but the time has come to move on without him. Remember, HE made the decision. The Packers gave him plenty of time to decide either way, and HE made the choice.
Now, if Rodgers did get injured (which i hope doesn't happen) I would say "why not?" to bringing Favre in to finish the season. But i don't think he would be in shape physically to do so. He would probably take a long time to get back into "football" shape. It would leave him open to more of a chance of a bad injury, as he wouldn't be physically prepared to play.
He worked his butt off all last off season, so he could be ready to play the 2007 season. He hasn't been doing that now.
Just my humble opinion of course.
