IRVING, Texas -- It might be easy for DeMarco Murray to feel pretty good about his rookie season after rushing for 897 yards on 164 carries, but it sure does not sound like the second-year running back is satisfied.

“The approach is the same,” Murray said. “At the end of the day I’m still the fifth or sixth running back taken last year, third-round pick, looked over by many and I’m still working to get better. I’m not a veteran. I haven’t been here for many years, so I’m trying to work hard every day and prove to myself that I belong here.”

Murray was the sixth running back taken in 2011 behind New Orleans' Mark Ingram (No. 28), Arizona’s Ryan Williams (38), New England’s Shane Vereen (56), Detroit’s Mikel Leshoure (57) and Miami’s Daniel Thomas (62).

Murray, who missed the final three games last season with an ankle injury, was the 71st pick but the leading rookie rusher. He did it all without the benefit of an offseason program and missed almost all of training camp with a hamstring injury.

“This is huge for me,” Murray said of this offseason. “I don’t have a chance to get the OTA sessions last year, learning the plays, getting comfortable knowing the offense and my teammates. This is a huge, huge blessing for me. I’ve been learning every day constantly. It’s been great.”
