Cam Newton is not nearly as accurate as Tom Brady was when he won those SB rings. Especially the last two. But they are both guys who were playing well, and had good defenses that usually gave them a chance to win. It remains to be seen if Cam can win a shoot out against an elite defense in the playoffs like Brady did (ironically against the Panthers).
Brady 2001 completed 63 percent of his passes, Cam is at 61 percent this year
Brady was 18/12 Cam is 24/13 td/int
Brady's passing rating was 86.5 Cam is 88.8
Add in Cam's 6 rushing TD's his 30/12 one the year, a dual threat in the playoffs a better player than Brady was that year the won
All I'm saying is defense win champions, and Cam is better than trent dilfer who held it together for the ravens
