Top NFL Draft Prospects: Oklahoma's Perine bullish among loaded RB class.

With a heavily muscled frame including anvils for limbs, Perine certainly looks the part of an NFL workhorse, and it is his power and pad level which consistently stick out on tape. Perine attacks the hole when it is there but shows patience to allow his blocking to develop, as well as the vision and anticipation to set up cut-back lanes when he feels the defense overpursuing. He runs angry, dropping his shoulders into oncoming defenders and keeping his legs churning through contact, rarely going down to the first hit.While incredibly productive in Oklahoma's scheme, there are concerns about Perine's ability to match this success in the NFL. While built like a cinder block, frankly, Perine also moves like one at times. He does not possess ideal speed to beat NFL defenders to the edge and lacks a second gear to qualify as a traditional breakaway threat, which could earn him comparisons to former Alabama standout turned NFL bust Trent Richardson.At first glance, it would seem obvious that Perine would make the early jump to the NFL if he enjoys another spectacular season for the Sooners. With "other" underclassmen stars at the position like LSU's Leonard Fournette, Florida State's Dalvin Cook and Stanford's Christian McCaffrey among the competition also likely heading early to the NFL, however, Perine may have to prove just as impressive in predraft workouts to earn the high pick his production would seem to warrant.
