But how much of that is McGahee's fault, and how much is due to the coaches being idiots?
I'm not saying it's not McGahee's fault, mind you...just that we really don't know.
Don't forget, though, that Adams was inactive for at least one game, and barely (if at all) played in several others. They probably got about eight games worth of play out of him...which is still pitiful, mind you. But "16 tackles in 16 games" isn't quite the whole truth.
