Better "runner" - Helu
Better back "overall" - Lucky
Depends on the situation to me. As for the current situation, I say Helu. Why not, based on the current rotation we should see all three backs in turn. Maybe the loss of his starting spot will "light a fire under his ass" (Lucky).
I still believe though that Lucky will be a key part of our offense. And as for Castille, where is the big man I wanna see some mizzou guys get their sh#t rocked (As for mendoza, that is a good question, he has some serious wheels though )
GO BIG RED!!!!!!
