We find the Offensive Rookie of the Year talk interesting because it centers around Cam Newton and Andy Dalton. Obvious Tebow isn't eligible because he's in second season, but this is for all intents and purposes his rookie year as well.
Look at Newton's and Dalton's stats at the Pro-Bowl voting page (and yes, you can vote for Tebow there...and more than once.)
Unlike Dalton and Newton, Tebow has only started 6 games and has a record of 5-1.
Dalton has started 11 games and is 7-4.
Newton has started 11 games and is 3-8.
Which would you rather have?
