Clifton Smith and Earnest Graham may form a "Rocket' backfield under new offensive coordinator Greg Olson, according to Cadillac Williams.

The Bucs have four tailbacks -- Williams, Derrick Ward, Graham and Smith, who is primarily a kick returner.

But Williams said the Bucs are expected to use a running back by committee approach that could include Graham and Smith in one pairing.

“I think coach Olson kind of just expands the playbook,’’ Williams said. “He’s going to get Peanut more involved in one of those rocket backfields. I think we’re going to be good. We’re still running inside, running the ball, play-action.''
