QB's I would list ahead of Favre are:
Manning
Brady
Palmer
Romo
Hasselbeck
Big Ben
Bulger
Brees
Cutler (this might be a bit of a homer pick, but this kid is a stud and actually draws a lot of Brett Favre comparisons)
Delholmme (people forget how good he can be when healthy and with only one good WR and no solid running game)
McNabb (this is debatable IMO, not a big fan of his anymore)
Eli Manning
That's 12 QB's and then I would throw in fliers that I think could be better than Favre this season. Guys like Leinart, Rodgers, Schuab, Garrard, Rivers, Anderson or even Brady Quinn might be better right now if he was given a shot.
Favre is undoubtedly one of the best of all time, but like someone's said he's only had one good year in the past 3-4 seasons, and he still threw too much INT's and a big one when it counted. We both know that's a throw Favre would have NEVER missed in his prime. It was a simple out pattern and he made a throw that cost his team the season. Would they have been there without him? That's debatable because they have so many good players on both sides of the ball and got great play from their secondary all year, but I doubt it because Rodgers needs experience.
If they start Rodgers now they might miss the playoffs this season, but in 2-3 years they'll be contenders for the Super Bowl again if they can keep the team intact, which shouldn't be too hard. All this kid needs is experience to become a star.
