Buccaneers' Coach Jon Gruden has called running back Cadillac Williams' comeback from last year's knee injury amazing, according to The Tampa Tribune. "It's one of the most amazing comebacks that I've seen," Gruden said. "He hasn't come back yet, but he is banging on the door. Our fans would be proud of him." Williams suffered a career-threatening knee injury on Sept. 30, 2007, against Carolina, tearing his patellar tendon after sprinting up the field. "He's ready to go now, if you ask him," Gruden said. "He's really putting some good tape together in his individual workouts ... the explosive movement appears to be coming back. Change of direction, confidence, stamina, all those things day after day after day a running back has to do are coming to him. That's what's really exciting."
