This is definitely something worth monitoring. Cleveland has a great OLine, especially when it comes to run blocking, so you know whoever they give the majority of the carries to will have at least RB2 value. My gut is telling me Hardesty is going to be the guy they try and feature. Why trade else would they trade up into the early 2nd round and snag him? I watched him quite a bit this past year and he looked good playing behind a patchwork Vols OLine even with teams stuffing 8-9 in the box because of the lack of the Vols passing game. What sticks out about Hardesty the most to me is that he is an exceptional pass catching/pass protecting RB. He may lack game-breaking speed, but he can move the chains and play on all 3 downs. He is also a perfect fit for the Browns zone-blocking scheme because he ran in a similar scheme in college and he is the best 1 cut and go runner in the draft.
With all that said though, you can't just brush off what Jerome Harrison did this past year in the final 3 games even if it was against the Jags, Raiders, and Chiefs (all terrible rushing defenses). I don't think James Davis will play a big factor in this competition. If he was as good as advertised, I don't think the Browns would have traded up to get Hardesty. Just my 2 cents.
