Eh, I disagree, I think winning a Heisman and a National Championship will net him a pretty decent amount of coverage for a (probably) second rounder.
Sometimes stuff like that can get a guy covered more than the average post-1st rounder, in large part b/c he's already such a household name. Talking about him brings in a larger portion of the audience than talking about some DE from Auburn, who might go in the top 10 but a lot of fans outside the SEC have never heard of before draft day. Look at how much Marcus Vick and Maurice Clarett got talked about (now, to be fair for them it wasn't b/c they were famous but b/c they were infamous, but still, the principle still applies I think). We'll see. I think he'll get talked about, in part b/c I have absolutely no doubt in my mind ESPN will find some nut to try to make it sound like he should be a top 10 pick.
