Why Big Three are struggling

The 2012 NFL season has begun with more of a whimper than a bang for Tom Brady, Drew Brees and Aaron Rodgers. While the trio led the league in Total QBR in 2011, none of the three are ranked in the top 20 so far this season and all three are being outperformed by the likes of Kevin Kolb and Ryan Fitzpatrick. The trio's collective 2-4 record after two weeks stands in stark contrast to their collective 5-1 record at this point last season. Each quarterback is facing different challenges that have caused his fall in the rankings (some within his control and some not), and each one has his own path back to the top. However, while Rodgers and Brady should be able to regain their form, the path back to the top is more difficult for Brees.
