Not even notoriously loose-lipped owner Jerry Jones is mentioning Emmitt, as in Smith, and Dallas Cowboys running back DeMarco Murray in the same breath. Yet.

Murray stepped up with Felix Jones injured and pirouetted through the St. Louis Rams’ alleged defense for 253 yards — a franchise rushing record that has been held by Tony Dorsett and Emmitt Smith.

A third-round draft pick out of Oklahoma, Murray also had the highest yardage total in the league this season, the ninth-most in NFL history. He had a 91-yard touchdown run that was the second-longest in team history. And he replaced another big-name running back, Jim Brown, atop the list of leading rushing performances against the Rams.

“I never thought in a million years that I’d ever have a day like this,” Murray said (via the Dallas Morning News). “This is what I've been working hard for since my Pop Warner days.”

In the interests of keeping the rookie’s feet on the ground, it must be pointed out that the winless Rams have the NFL’s worst defense against the run. They were allowing 163 yards per game.

“It's easy to run the ball when you're not making tackles,” Rams safety Quintin Mikell said. “When you're not getting guys on the ground, there's not much you can do.”

So, can the “Emmitt” talk.

“I don't want to make a comparison there,” Jones said. “I just want to commend Murray on a great day and the offensive line and the fullback. It was a real team effort to get him those yards. I am proud for everyone concerned there. He's certainly worked hard. He obviously has some uniqueness about him.'”

Dez Bryant was more effusive. “Outstanding. Great. Amazing. I can keep going,” he said (via the Fort Worth Star-Telegram). “He did an outstanding job today. Hey, he said he needed an opportunity. He got what he wanted, and the rest is history.”
