Ryan Torain's big game against the Rams in Week Four appeared to signify a shift in the Redskins' backfield, but it might not be quite as dramatic as the fantasy football folks would have you believe. Torain ran hard and through contact, and his energy was a big catalyst in a game where the offense came and went in spurts. But is he the meat-and-potatoes back? Not exactly. Expect Roy Helu to mix in, with the two alternating blocks of series; you might see one back for 20 straight plays, for instance, not counting third-down snaps. Torain has great burst through the hole and more power, and Helu provides better speed for breakaway potential. And about those third-down snaps, those very well could go predominantly to Tim Hightower, who appeared to lack stamina in a full-time role, but his well-balanced game and good pass-protection skills would serve the team best in nickel situations.
