I wouldn't rely on draft grades as the gauge for where he would have been drafted. (outside of first round; maybe 2nd) Scotty M. said he was the highest ranked player on the board in the 3rd and he would have taken him a round earlier (was surprised he lasted). They clearly don't have the same draft boards as Mayock and Kiper who simply rehash the same **** over and over.
Florida had a terrible offense with no threat of passing the ball at all. I wouldn't say Jones wasn't that good, he averaged 5 yards per carry and dominated Tennessee and Georgia. Look at the LSU game, Jones got 4 carries, Taylor got 2, and Driskel got 21!
I don't think he's a great prospect, but he should be a solid NFL back that can move the chains. He's a big, strong, physical runner. He probably wouldn't fit many zone blocking schemes.
edit, the guy Scot compared him to was Frank Gore
