Debate about the running backs will be enough to hold this site over for the offseason alone (and that's not considering endless discussion on the BCS 'chip just won, signing day surprises, and QB debate).
I love the addition of Bryant because it makes the picture even more muddy.... in a great way.
You've got GAIII who could be a feature back if he improves in pass protection and reading the lanes; you've got Carlisle who should be healthy and motivated after a year off; you've got the Battering Cam, still the sickest full-speed stiff arm on the roster; You've got Mahone, who could either be Jonas Gray all over again depending on what his focus is on the weight room; and now you've got Bryant coming in, a guy who can be Theo 2.0 except with a bit more power.
Any of these guys can give BK the production he wants, provided they all get better in the areas that they need for one to step up to that no.1 position. And there's no doubt that someone is going to be a star with the way the coaching staff gets these guys to deliver.
My ultimate favorite would be not 2 rushers close to 1000 yards, but 3 rushers all over 500. Fresh legs on every carry baby!
