Angelo Crowell started in Spikes' stead in 2005, and there is talk that he might move to the inside, but he's a useful fourth/fifth linebacker being stretched into a starting role.

It appears the writer Bill Barnwell / FootballOutsiders.com thinks he is no better than a #4 LB. Is he good enough to start on other teams? I think so.
