ESPN Say's Newton To Enter Draft

[warriorzpath]

After seeing a lot of reference back to Aaron Rodgers, I was trying to determine what was different about him and Alex Smith and Jason Campbell coming out of college in the same draft year.

They all seemed to be talented, even though Alex Smith was preceived to be on another level -- which was indicated by their draft positions. So it wasn't something that only the nfl scouts saw.

I know it wasn't about winning because in Jason Campbell's senior year, Auburn finished undefeated and ranked #2.

So what was it in Rodgers that was different coming out of college -- that we should look for in a qb coming out of the draft this year (or any other year for that matter)?

Or is it an intangible trait that you can't really measure or discover until after the qb's been drafted?
