Strengths

• Shows a surprising burst to beat linebackers to the edge. Can plant his foot in the ground and explode, showing better straight-line speed than expected.
• Possesses quick feet and straight-line speed but doesn't have the elite burst to be a constant big-play threat. Improving patience as a runner, following pulling guards and makes good decisions on his cut.
• Does not possess top breakaway speed, though he's rarely caught from behind.
• Flashes initial burst and good lateral quickness to sidestep defenders or bounce runs outside with very good foot quickness. Displays very good feel as an inside and outside runner with above average vision to make sharp cuts - good patience· and footwork to pick through defenses.
• Not truly explosive, but possesses enough speed to beat linebacker to the edge.

Weaknesses

• Too indecisive and hesitant at the line of scrimmage.
• Offers little in pass protection and poor technique cut blocking, fails to do more than slow down blitzers by laying down in front of them.
• Does not always read blocks behind pulling guards. May not be big enough to move piles at the next level and has a tendency to bury his head too soon.
• Has a lean frame and lacks ideal bulk or muscle for the position. Doesn't have great strength, lacking a power element to his game to break many tackles.
