The only thing that sets Cam apart is his athletic ability, and ability to run. The system Gus runs is designed to put up monster stats, no matter who is playing qb, he will change the scheme to suit their strengths, what he did passing at Auburn doesn't mean nuch as far as the NFL is concerned, because nothing they ran resembles an NFL offense.
There are different types of spread offenses, which some people seem to get confused about, there is the zone read/option kind that guys like RichRod runs, the Airraid that Leach runs, and then stuff like what Oklahoma ran has pro concepts that the Saints/Patriots/Colts run as well as what McCoy was running at Texas. No two spread teams are identical, although the system at Auburn is similar to what Urban Meyer had for Tebow. Gus is like a mixture of Leach/RichRod/Urban Meyer. He has been wanting to run more option stuff, even while at Tulsa, but never had a qb that was a good runner. I wouldn't put much into his passing stats. He is a good athlete though. The question is, does he have the work ethic and dedication to the game to make it as an NFL quarterback. Will he be able to transition? This isn't about race, the same questions were there for Tebow.
