Oh yeah. That fullback thing is very noticeable. It didn't happen with Hillis once he started a few games so here's hoping that this label will go away with time.
Riggins was (allegedly) a party animal whereas Alstott was a VERY hard working guy. I definitely think Alstott would pull better numbers but in terms of raw talent I would think number 44 had the edge. I loved how Mike got his SB ring and even scored the first TD of the game back then.
