So much delusion in this thread.
In a Favre-Rodgers comparison, of course it's Rodgers.
You can't use career statistics (totals, that is) given that Favre played more seasons than Rodgers has played to this point, but when you take averages into consideration, it's not even close. Lets see...
Completion % - Rodgers
YPA - Rodgers
TD-INT ratio - Rodgers
Passer rating - Rodgers
4,000+ yd seasons - Rodgers (done it in 75% of his total full seasons, would have done it in '13 if not for the injury)
All things considered, Rodgers has the better playoff numbers as well.
Now, to be fair, Favre did win three consecutive MVP awards, highly impressive. Rodgers has 2 so far. Favre has won more playoff games, but he and Rodgers both have a super bowl apiece. And Favre does have an extra appearance in the super bowl, so Rodgers could easily eclipse those numbers with more seasons (he's only 32)
Also, Rodgers is a super bowl MVP. Who was the MVP of the Super Bowl Favre won? It certainly wasn't him, completing just 51% of his passes. Maybe he had a lot of drops in that game that I don't recall, but I know that Rodgers' 24-39 included SEVERAL drops.
This does it for me - Favre had 66 interceptions in his first 65 games as a pro. Aaron Rodgers has 69 interceptions for his career, which includes 132 games. Give me the quarterback that takes care of the football better. I'll win more with him.
And oh by the way, Rodgers has something going for him currently that Favre can't say. Rodgers has yet to miss the playoffs as a starter in the NFL. EDIT: Captain correctly pointed out 2008, my bad.
I mean, pretty much any metric or statistic that you wish to use, Rodgers comes out on top in a comparison between the two.
