  • 9 3/4" Hands


Nicknamed "Taz" after the Tasmanian Devil due to his non-stop movement.



Played in pro-style attack. Patient runner. Has feel for the hole and a sense of timing on when to burst. High school high-jumper. Has hip explosion and enough suddenness to shake a downhill safety and long speed to finish with a big play. Impressive feet that jump cut, side step and reset with ease. Can make tight moves. Proved to be dangerous out of the backfield. Consistent production while playing for a consistent winner. Tenacious, with strong desire to succeed. Big personality with loads of confidence.


Runs upright through the hole. Play strength below average for listed weight. Doesn't generate power in legs and fails to break many tackles. Willing blocker but struggles to anchor in pass protection. Pad level and lack of strong base could cause him to take bigger hits than most runners. Worked hard in 2014 -- coming off of a 398-touch season in 16 starts.

Bottom Line

Patient, pro-style runner with the potential to be a full-time backup and play on all three downs if asked. Play strength is below average for the position, but he's a creative runner who can find yards on his own and catch the ball out of the backfield.
