For one of the rare times in his football life, Brady Quinn was a game-day spectator. Instead of a helmet, he wore a brown-and-orange baseball cap. He carried a clipboard. Quinn stood on the sideline and watched, maybe for one of the last times. Tagged since April's draft as Cleveland's quarterback of the future, Quinn could soon become the Browns' man of the moment. In the aftermath of a 34-7 drubbing against Pittsburgh in Sunday's season opener, Cleveland coach Romeo Crennel didn't rule out Quinn making his NFL debut this week against Cincinnati.
