Quality depth is a huge difference maker. Take linebacker as an example. If this were CNS year one at Alabama and one projected starter (Fanney) had left the program and another one had gone down with a season ending injury, as Hightower did, and a key reserve (Harris) had been suspended for half the season we would have been in an Auburn type situation, having to use walk ones and/or true freshmen. With all that happening to us this trip around, we just plugged in another quality player and didn't miss a beat. Deaderick gets shot? That is just more snaps for Dareus.
I've probably said this before on this board, but perhaps CNS biggest accomplishment at Bama so far has been taking average football players such as Anders, Reamer, Johnson, King etc and making winniing football players out of them. Congrats to Marquis on stepping up big time against SC.
