In the right situation, I think Aaron Rodgers could absolutely win another Championship, maybe two. Give him a defensive lead team with solid coaching that doesn't ask him to do too much, and he'd be hard to stop.
I actually wouldn't mind seeing Rodgers traded. Not because I think he sucks or I don't like him. I just don't think he's going to win another Super Bowl in Green Bay, and I think it'd be awesome to see him win one more, even if it is somewhere else (if the Packers can't win it that year). He has his issues, but I'm still a big fan. I'm surprised Rodgers didn't structure his contact to give him more flexibility for evaluating other options late in his career, if needed. Why not?
