Buffalo, left guard: Third-year veteran Mike Pucillo, a blue-collar guy with a superb work ethic, won the job in the offseason. But then he proved susceptible to the bull-rush in a scrimmage and the first preseason game, and suddenly Lawrence Smith, who has been a bit of a football nomad, began coming on. New line coach Jim McNally is famous for turning afterthoughts like Smith into players and, for now, the unheralded lineman is running with the first-unit offense.
