Consider Mark Schlereth, who spent six seasons as a Denver Broncos offensive lineman, protecting quarterback John Elway en route to two Super Bowl victories. In a 1998 playoff game at Kansas City, Schlereth and his fellow linemen coated their arms and the backs of their jerseys in Vaseline. The Chiefs' defenders couldn't grab onto the slimy Broncos and quickly complained to officials. It was quite a scene, Schlereth recalls, as officials used towels on the sidelines to wipe down the oily visitors in a game Denver would ultimately win, 14-10, on its way to a Super Bowl triumph.
"Did I grease up my jersey, and use sticky substances on my gloves? You're damn right," Schlereth said recently. "What you call cheating is a fine line. It's an interesting line. What we did, in the locker room, is called being creative. Certain cheating is snickered at, or applauded."
