UMdad started the QB thing, which is still going. It was kinda fun so here's one that should not be nearly so debate prone, but interesting nonetheless for June. Who was the best M RB? I will twist it a bit though: I'm defining "best" as the most impressive M running back you've seen play. As in, "holy shit that guy's good." As in talent. As in impressive either in speed, moves, toughness or all three and more. So stats are legit, but stats won't be definitive on this topic under this definition.
The most impressive M RB that I've seen play: Tyrone Wheatley Second: Timmy B. Flame away.
