Dotson certainly looks far better than his ranking suggests. In that regard, he reminds me of the unheralded tackle from Kentucky that signed when Rich Brooks was here. I can't remember his name right now for the life of me, but the guy was regarded as the best OL on the team when he was a freshman, despite coming in as a 2 star prospect. Was his name Murray perhaps? If I remember correctly, he was only here for a season or so. Not sure if he was an academic casualty, got suspended, or was injured, but he sure could play.
ETA: It was Aaron Miller I was thinking about, from the 2004 class.
