It's an ESPN Insider link, so here's the text:
Newton silenced his critics with a great rookie season. He has all the physical tools you want in a quarterback: size, speed, arm strength, escape ability and physical strength. He is huge and has the kind of foot speed and quickness to avoid the rush, extend the pocket and make a good throw on the move. He needs some work on refining his mechanics when he does not have time to set his feet under him, but he has enough of an arm to make all the throws without getting set. He needs to work on going through all of his progressions and hitting the most open receiver; he will tend to force the ball now and then. With normal progression he should develop into an elite quarterback who can carry a team.
By comparison, Aaron Rodgers is rated a 97, Payton Manning is 90, Tony Romo is 85, and Matt Stafford is also at 84. Matty Ice is 83 along with Vick.
