Bills vs. Cowboys: DeMarco Murray Riding A Hot Streak

In the past three weeks, Dallas Cowboys rookie running back DeMarco Murray has emerged as a star. Filling in for injured starter Felix Jones, Murray has run for 466 yards at a whopping 8.5 yards per carry, and the Cowboys are 2-1 in those games.

Granted, Murray has done most of his damage against NFC West bottom-feeders St. Louis and Seattle (and he added 74 yards on eight carries against Philadelphia and their No. 23-ranked run defense). Still, that's outstanding production no matter the circumstance, and it makes one wonder what his role will be when Jones returns to the lineup. Jones may not be ready for this week's game against the Buffalo Bills, per Dave Halprin of BloggingTheBoys.com.

"At the time I'm writing this, I don't think Felix will be healthy enough to play," said Halprin. "If he does, I think that the Cowboys would be insane not to keep featuring Murray as the lead back. Murray has been unbelievable in the last three games; he's a complete back. Felix is explosive, but injuries have marred his career. I think the Cowboys need to learn that limiting the touches for Felix is probably the only way to keep him on the field and productive. He should be more than just a third-down back, but Murray's carries should be substantially more over the course of the game."

Time will tell if Murray is as much of a handful for Buffalo's improving run defense as he was for the league's cellar-dwellers.
