Gotta look at how good a team each QB plays on to determine who's the best. Is Brady REALLY that good? Or is he just "good" and has been playing on the best TEAM?
You can't really say that until he plays on a mediocre to bad team and still puts up some numbers, like Favre or Marino. Remember how people were saying Favre was washed up just two seasons ago, when the Packers were terrible?
Well, he obviously was the same player, just didn't have any teammates.
Look at Philip Rivers....Norv Turner has ruined the Chargers, and Rivers is taking a lot of the heat. Nothing wrong with Philip...he's still a better QB than either of his draft compadres, Sheli or Worthlessberger, but his team is killing him. I don't see too many people blaming LT when he's averaging 30 ypg less than last season. But Norv Turner is the problem. He sucks a head coach, and now Chargers fans probably wish Marty was still there.
The Giants will be okay if Eli can develop into an average QB like Phil Simms was, who can just run the offense and not give games away, and let their defense stuff the other teams. That's all they can ever expect from Eli.....he's never going to be a gun-slinging, Elway-esque, come-from-behind-shootout kind of QB.
