‘No one knows how Mularkey came up with this idea that leaving teams guessing whether it’s Kelly Holcomb or J.P. Losman waylays their preparations. But I have a theory. Remember the final game of last season, when the Pittsburgh Steelers refused to divulge how much they’d play their starters? And the Bills had no choice but to game plan for their regulars? And then the Steelers decided to play predominantly their backups? And the Bills got their butts kicked? Guess you’d have to say Bill Cowher wrung at least 10 percent out of that little caper.’
