Philadelphia Eagles coach Chip Kelly thinks you're a better fit for his offense as a "one-cut runner." What does that phrase mean to you? Is it something that comes naturally, or did you have to work at mastering that style?

DeMarco Murray: I've always kind of been a one-cut, get downhill as fast as I can. It's hard to go East and West in this league. A lot of fast guys. In order to get a lot of yards, get a lot of production for your team, you've got to go North and South.

How much did rejoining your Oklahoma teammate, Sam Bradford, have to do with your decision to come to Philadelphia? Were you concerned after hearing so much speculation about Marcus Mariota in the draft that Bradford might be moving on?

Murray: Sam's a great friend of mine. He's like a brother to me as well. We've spent some time at Oklahoma; we were roommates there. We played a lot of great games in Norman, so it was a huge influence once I heard that he was getting traded here. He immediately texted me and said, 'Hey, jump on board. Let's go win it.' I'm excited to get back with him. He's a close friend of mine and I'm excited to play with him again.

If Sam was worried about the draft, he didn't let on. He has been all business, so that's the atmosphere around here.

You led the NFL in rushing [in 2014], yet the Cowboys were willing to let you walk in free agency. They seem to believe their offensive line was the reason for last year's success. Does that motivate you to prove it wasn't all the line?

Murray: I'm always motivated to help my team. Every great running back has had a great offensive line. There's a great offensive line here. I've been out here for a few weeks now and they're looking good. Coach Stout [Jeff Stoutland] is a very smart coach and he gets the best out of every guy on that line. JP [Jason Peters] and [Jason] Kelce are two older guys who have had a lot of success in this league. The younger guys are starting to follow them. Great group of offensive linemen. They really work hard.
