Cliff will forever be remembered by most who knew him for his constant and radiant smile. It came from an inner well of confidence that both fueled his play on the field and dictated his personality off of it. “I had to be careful with Cliff,” Hall of Fame QB Ken Stabler once wrote. “He had so much confidence now that he was always telling me he was open. We’d be coming out of the tunnel to start the game, and Cliff would start claiming he was open.” Stabler might have been joking, but that swagger genuinely endeared Cliff to his teammates; it made him who he was.
