That's fine... I'd rather see Bishop and Coleman in there learning and improving.
Not a big loss at all. Bishop is as good against the run as McClain is and Coleman is better against the pass than McClain is.
Coleman is flying under the radar a little bit, but that guy actually has the physical talent to be a pro bowl caliber DT in Marinelli's defense. I mean extremely talented. If he matures some and keeps his head on straight he is going to be a force inside.
Even though Davon is only 6-2, he has the arms of a 6"4' or 6"5' guy, and he is about as quick twitch a DT as you'll find.
