Raiders coach Dennis Allen said Tuesday at the NFL owners meetings that he's not sure what second-year running back Latavius Murray is capable of, but he's looking forward to finding out.

Murray missed his entire rookie year with an ankle injury, but he's expected to compete for a role as the No. 2 running back behind Darren McFadden this season.

"Latavius is a guy that I think has a lot of potential," Allen said. "When you look at him from an athletic standpoint, he’s a little over 6-2, he’s about 230 pounds and ran a 4-3 40-yard dash. He had the injury last year, and he was never really (healthy). When I saw the tape from him in college, I was very impressed with him as a runner. He's a big, physical back that has excellent footwork and lateral movement. And he has good vision.

"The problem is I never really saw Latavius Murray from the time that he walked on campus. Because really even then in the rookie minicamp he wasn't 100 percent healthy. From all indications, he’s healthy now, and so I’m excited to see what he can do."
