Former Eagles running back LeSean McCoy recently fired a shot a current Eagles running back DeMarco Murray, saying, “I think Murray’s good. But I don’t see him as competition as far as the best backs. I like my game a lot.”

Murray has responded.

“At some point you’ve got to move on with your life and career,” Murray said of McCoy after practice on Thursday, via CSNPhilly.com. “I never worry about what someone else says about me, good, bad, and ugly. . . . I can only control what I can control, and I can’t control what someone else says about me.”

Murray is right, but it’s hard not to wonder whether Murray is using that to motivate himself as he prepares to debut as the successor to McCoy.

It’s also hard not to wonder whether McCoy will decline to move on.
