Drew Brees is a student of the game, Chad Henne isn't. Drew Brees is a gym-rat, Chad Henne isn't. Drew Brees want's to prove something, Chad Henne doesn't. Drew Brees is "smart", I'm not so sure about Henne.
Chad Henne IMHO, just doesn't have that "it" factor.
It's something you can't teach, heck even Tim Tebow in his 2nd NFL start out played Henne in the same week and got his team a win.
Henne on the other part, can't even hold on to a 10 point lead with 4:51mins left in the 4th quarter, in a meaningless game, meaning there should have not been any pressure on Henne to have to prove anyhting.
I am more amazed how some fans are still in denial.
