As much as I love and respect Starr, those teams were more about rushing and defense. Starr is probably one of the most under rated QBs in history, though.Bart Starr won five world championships in a seven-year span.
For that matter, at this point I would say Favre is probably underrated as well. For all his mistakes, he could throw a lot of TDs and win a lot of games.
I'm sure most people (myself included) would take Rodgers though.
Favre going to Minnesota didn't really bother me. That was the best destination for him at the time. The overtime playoff game against the Giants where it was intimated that he gave up because of the cold was more annoying to me.
Favre's teams had better defense, but Rodgers has probably had better receivers.
Big question: Who has had the better coaching?
