I don't know whether he is/would be any good but just because a guy is fast and elusive doesn't automatically make him a good kick returner.
Punt returning particularly is a whole different animal than virtually anything else on the field. The best one in NFL history, Devin Hester, basically couldn't play any other position.
I'm pretty sure now that we have a accomplished coach on the special teams side there will be the best guy back there, who ever it is.
