I chose Breece but perhaps it was recency bias. Both were great backs. Breece had better top-end speed and, in my mind, was more versatile.
Ron Dayne also had 2 seasons of over 2000 yards ('96 and '99), but Troy is the only one to do it in back-to-back seasons if that counts for anything.
He knocked teeth loose from what I heard.Schemes may have been tough for him, but he actually was fairly decent in pass protection. He didn't mind hitting a linebacker head on. I can remember coaches praising him for that latter part.
