Well I've been absolutely tearing apart the Internet and this is all I have to show for myself.
It could be him...this picture was from 2000, when Clayton was a senior in high school I believe. Although I'm not sure who exactly that Sam Houston player is in the picture, it's a varsity player, and I assume Clayton was on varsity as a senior. And that kid definitely looks like a wide receiver.
If you want any more pictures from that game here's a link. Unfortunately that site is for the other team, so most of the pictures are of players on the other team...this is really the only picture out of the bunch that I found that has a chance of being Clayton.
