For one, Arkansas' Knile Davis was measured at 5'10", 227 pounds at the 2013 NFL Scouting Combine.
Secondly, he was clocked at 4.37 seconds on the 40-yard dash and pumped out 31 reps on the bench press.
Clearly, this guy possesses the size, speed and strength trifecta to punish defenses and outrun defensive backs. If there's any concern, it's simply his durability.
Davis accounted for 1,458 total yards in 2010 and scored 14 touchdowns.
So, the 2011 campaign was expected to be incredible. Unfortunately, he missed the entire 2011 season because of an injury, according to the Razorbacks' official website:
University of Arkansas junior running back Knile Davis sustained an injury to his left ankle during practice Thursday evening and is expected to miss the 2011 season.
Returning to the gridiron in 2012, Davis collected 534 total yards but missed some time from a pesky hamstring, via Chris Breece of 5NewsOnline.com:
He saw little contact in practice last summer and was never fully healthy for the 2012 campaign. Davis battled a hamstring injury throughout the conference season, which limited his carries and yardage.
The tangibles exist for Davis to have success. It's a matter of remaining consistently healthy.
