Redskins coach Mike Shanahan believed that running back Roy Helu had something special, so Washington traded up to take him in the fourth round of this year’s draft. The Nebraska product looked good in the preseason, and on Sunday cranked out 112 all-purpose yards.

Starting running back Tim Hightower praised Helu’s performance after the victory and Shanahan said Monday that he also was impressed by Helu’s game.

“When you’ve got a guy like Helu, you don’t know why guys make plays, but the great ones do,” Shanahan said. “I think Helu is giving people ideas that he can make plays. He’s got some speed, some running ability and it’ll be an ongoing evaluation of him. Can he pick up blitzes? Can he hold onto the football? But I was pleased with what he’s done through the preseason and our second regular season game, and hopefully he continues to grow.”
