The NFL is arguably the roughest, and toughest sport in the world today. Calling an offense effectively with 300 lb. behemoths coming after you is not only tough, it is down right courageous. Some of the greatest Quarterbacks in league history never won, or even made it to the Superbowl. This list is based on a quarterbacks on- field abilities, and there ability to call an offense.
Let me begin by saying that I utterly hate Tom Brady and the Patriots. But I gotta give em' their due's. Brady has become an amazing future Hall-Of-Fame quarterback under the tutelage of Bill Belicheck. If Brady was never injured last season the Pats would've easily been the champs. The man knows how to call an offense and has pretty decent wide-outs as well. Tom is going to come into this next season with a vengeance, anything less than the Lombardi will be a failure for him.
Peyton in my opinion is surely underachieved. Than man should have at least five rings by now. I don't know how his next season is going to be, being that he is without Marvin Harrison. This man is the king of audibles, heck the colts don't even need an offensive coordinator, he can do it all by himself. As long as he is around the colts will always have a good offense.
Big Ben has solidified himself as a legitimate threat to any and every defense. Very young, and he already has two rings. So far he has done a lot better than his draft day counterpart in Eli Manning. Although the Steelers didn't have the best offense last season, Ben and co. were able to ride the coattails of the most feared defense in the AFC, and make the plays when it mattered. Although I don't see any team in the AFC doing better than the Pats this season, the Steelers will once again be considered contenders, thanks to Big Ben, and the steel curtain 2.0
Eli was hiding in big brother Peyton's shadow for a long time. Until the last couple of seasons he could'nt shake the assumptions that he can never be as good or better than his sibling. But for now he has silenced his critics, winning the biggest game of his career in 2008 on a couple of miracle throws. His improving leadership, and on-field skills make this guy an elite quarterback, and if he continues to improve he will join older brother Peyton in the Hall-of-Fame.
McNabb is one of the more versatile QB's in the league. His injuries have made him change his game and that has attributed to his true value. How many players do you know can change their games and be just as effective if not better? After a few dissapointing seasons the Eagles once again find themselves in contention, thanks in part to a healthy McNabb. Earning a trip to the superbowl was the highlight of his career, but look for them to in the Superbowl talk once again.
