One the "negatives" about playing AB is if you're a great blocker and the other ABs are so-so at blocking, you're going to sacrifice some carries to open the way for other ABs. Roddy Jones was a great example of that. Dude ran for over 200+ yards his R-Fr year against UGA and really never had a big game after that. Part of it was because of circumstance, but a large part of that was because he was the best blocker of all the ABs during his time here. CPJ has said on more than one occasion that Orwin Smith was the beneficiary of having Roddy Jones blocking for him.
