I haven't been able to find a photo that's not copyrighted. You can see a few on MaxPreps: http://www.maxpreps.com/athletes/giY...wame-clark.htm. Rep if someone can post a photo I can copy into his profile.
Clark has been largely ignored because his main position was runningback and he's behind all-everything Malcolm Brown on the depth chart. (That's kind of like being Adrian Peterson's backup when he was a Texas prep.) Clark did get some action last year, though, averaging over 7 yards per carry on 40 carries. He was also in on a few tackles. Looks like he's now focusing on defense and CU is recruiting him as a corner. We are his first offer.
