As NFL teams continue to decide that running backs are fungible, there’s a belief in some circles that no running back, no matter how great a prospect, is worth a Top 10 pick. NFL Network’s Mike Mayock said after visiting Alabama’s pro day that he has no doubt from watching film of Richardson that Richardson is one of this year’s elite prospects, but not necessarily one of this year’s highest picks. "I think he’s a Top 10 talent," Mayock said of Richardson. "That doesn’t mean that I endorse taking him with a Top 10 pick. I have a problem with running backs, and the history of running backs in the last 6-7 years in this league, justifying a pick that high. The last Top 10 pick for a running back that has paid off in my opinion has been Adrian Peterson, who went No. 7 to the Vikings."Mike Mayock via PFT This sums it up nicely I think. T-Rich is a talented player, but based on the position, teams are hesitant to take a RB that high.
