Well, I'm going through 2005, looking for ROLB with the #42 who weren't seniors or didn't leave and I found:
Ricardo Hurley, South Carolina
Bobby Carpenter, Ohio State (we ruled him out though)
Rufus Alexander, Oklahoma (LOLB, but they could have him at ROLB)
Daniel Brooks, Tennessee
Those were the ones rated 80+.
So I have no clue.
