Arkansas running back Knile Davis is one of the biggest high  risk-high reward prospects of this draft. One thing I want to make clear  immediately: he’s underrated by the media. 
The media’s perception of  him is as a formerly good player that had a horrible ankle injury and  wasn’t the same upon returning, but remains a fairly good workout  warrior. But that’s not entirely true. Knile Davis wasn’t the same upon  returning for most of the season. But, in the last game of his career  (LSU), he looked like the Knile Davis of old in his 12 touches. He  looked like he hadn’t lost a step since his sophomore year. He still is  regaining his feel for the game, but, physically, he’s back. He’s 100%  back. It’s not just for the combine. It’s for the long haul. NFL teams  know that, and he’s going to find his way into the third round or so  this year. But he still has his problems.
Another think I would like to make clear: I’m not a doctor, now will a pretend to be one. I took a similar stance in my 
Michael Mauti scouting report.  The only thing I’m willing to say is that the physical effects of his  season ending ankle injury haven’t been apparent since before the LSU  game. Still, this may be a recurring injury. I don’t know. I wouldn’t be  the person to ask. Right now, he seems unaffected by it. NFL team  doctors might tell teams to bump him down their draft boards because of  the injury. Or maybe the X-rays look pretty good, and team doctors may  tell teams to bump him up. I don’t know. I’m not going to try to  speculate, because the last time I did, I called Rob Gronkowski  overrated (he gave me literally every reason in the world he had a bad  back, like, Dwight Howard bad, but boy was that a terrible call by me).  I’m going to try to be as neutral as possible regarding his injury  issues, because I know very little about his ankle, excluding the fact  that it was broken.
Davis has rare measurables. His combine was amazing. 5’10, 227lbs,  4.37 40 yard dash, 31 bench reps at 225lbs (That’s Steven Jackson  territory). He had the second fastest 40 at the combine among running  backs (Onterio McCalebb was best), and he did the most bench reps, an  enviable combination. He had small hands, and he didn’t do a good job  with the vertical of the broad jump (needs more strength in the lower  body), but still, his measurables are terrific.
Davis’s stats are mostly a mixed bag. His sophomore season was  ridiculous. He had 202 carries for 1322 yards for a 6.5 yards per carry  in the SEC (!), to go along with 13 touchdowns and 19 receptions for 136  yards. Honestly, had he not been injured in 2011, Arkansas could have  won the national championship, and he was more productive in 2010 in the  SEC than Trent Richardson ever was. Those numbers are incredible. But,  in 2012, he wasn’t the same player for most of the season. He had 112  carries for 377 yards (an ugly 3.4 yards per carry), and an inexcusable 7  fumbles. 7 fumbles. On 112 carries. As bad a number I’ve ever seen.  While I’m on the subject, I might as well put my two cents in on the  subject of his fumbles. This will be a long term problem in the NFL.  One, he has small hands. 8 5/8 in, 3rd smallest at the combine among  running backs, which is pretty insane given how many short backs there  were at the combine. That problem isn’t going to go away. In addition,  his ball carriage is pretty loose. He usually has two hands on the ball,  but his off hand isn’t really doing any more than simply laying on the  ball. It’s not applying any sort of pressure. It’s like the off hand in a  basketball shot. It’s not really applying much of a force. It’s  basically there for balance. And when your hands are as tiny as those of  Davis, you need to put as much effort into using both hands to secure  the ball as possible unless one hand is briefly being used to do a stiff  arm.
Davis is an elite athlete. I’ve always felt that, to be a superstar  running back in this league, you need to be powerful enough to inspire  fear in your opponents when you run inside as well as quick and fast to  inspire fear in your opponents when you run outside and try to turn the  corner. LaDainian Tomlinson and Adrian Peterson, two of the top backs of  the last decade, fit this mold. So does Davis. In his case. his  quickness is good but his long speed is just ridiculous. No guy should  be as fast as he is at that size. It’s really special. He also reaches  top speed quickly and has above average change of direction skills.  Still, as an outside runner, he has problems, because he doesn’t have  much patience and has an awful tendency to run out of bounds instead of  taking a hit, quite reminiscent of (gulp) Beanie Wells. This is a  terrible tendency. Because he is willing to run out of bounds instead of  fighting for more yardage, a corner will gladly concede the edge to him  (knowing they have no chance of actually tackling him) if the  linebacker isn’t there to help inside knowing that he’ll simply run out  of bounds when he sees the safety coming his way. The worst part is that  this isn’t just a post ankle surgery tendency. He ran out of bounds all  the time back when he was a sophomore, and now that he’s even more  worried about his health, he may not stop. It’s a big problem, and it  will hold him back in the NFL if it continues.
The other problem with running out of bounds is that it’s waste of  his power. Which brings me to my next point: he has a lot of power.  Although he lacks leg strength and can’t push the pile (he may have laid  off the leg press machine post ankle surgery), upper body strength is  absolutely ridiculous, and his core is nice too. It’s hard to knock him  off balance and he’s got a nice stiff arm. He’s powerful. He’s really  hard to bring down. He flashes toughness.  That being said, his vision  could be better. He’s impatient when he enters the second level, not  giving his blocks time to develop, though he really does a good job of  weaving through traffic and gets solid pad level.
Davis is a decent pass catcher. His hands are solid, although small,  he’s a half decent route runner, and he’s explosive in the open field.  He also is a capable pass blocker that plays with solid on field  intensity, though his ability to read blitz schemes is pretty average at  this point. In the long term, he should be pretty good on third downs,  though he probably won’t ever be a third down only back.
Davis has a lot of potential, but he’s got a lot to work on. Even if  he’s healed, he needs to stop fumbling (or at least fumble less,  seriously), running out of bounds to avoid taking hit, and become a  little bit more patient entering the second level. His ceiling is high,  but his floor is low.
NFL Comparison: Rashard Mendanhall, but with Chris Well’s vision and  also more injury issues. He needs to stop running out of bounds to avoid  hits. Oh, and he fumbles more than Mendanhall (I didn’t know it was  possible).
Grade: 71 (worthy of a late 3rd, maybe early 4th round pick)
Projection: 72 (will be a late 3rd, possibly early 4th round pick)
