Hell, he might be starting soon. All of the draft eligible guys are probably going pro now that Diaz is gone, and recruiting has taken a nosedive since Miami's mid-season collapse.
As far as I know, he's only ever seen the field on special teams in kickoff coverage.
I do remember reading a short blurb from Richt after the Savannah State game earlier this season, and he was praising that guys work ethic on the scout team.
