1. I can't be sure but it sounds like McGinn remembers Rodgers being Favre's backup for just two years and then Favre-a-palooza in his third camp. Actually it was his fourth (2005-08).
2. I don't have numbers or any other evidence, but my recollection is that Rodgers was not unequivocally bad during his first two years. And his performance in the Dallas game in '07 is what made most of us feel that he was the legit heir to Favre.
3. Great QBs who had lowly beginnings: Bradshaw, Fouts, Steve Young, hell it took Favre four full years (counting his first one in Atl) to gain Holmgren's trust and perform at his 1995-98 level.
4. logical fallacy: learning to be one of the guys and leadership are not the same thing.
