I think Moe is the safest pick of the three. He's a good goal line back, and has produced TDs (2002) and decent yardage (2003).
I'm not saying he'll be the feature in MIN, as Bennett is very talented; I just like Moe as a better value in the late rounds, as opposed to taking a bit of a chance on Bennett early.
