The winner? In a close call, we’re making it Buffalo over Pittsburgh, once again because the Steelers’ Jerome Bettis must prove he is beyond a 2001 groin injury. Buffalo is actually four-deep at tailback, with Travis Henry, Sammy Morris, Shawn Bryson and Richard Huntley. And that doesn’t even count Curtis Alexander, who had a terrific season in NFL Europe this spring, but probably won’t make the roster. The tailbacks are augmented by venerable fullback Larry Centers, never much more than an adequate blocker, but still one of the NFL’s premier receivers out of the backfield, even at age 34.
