Dolphins quarterback John Beck now appears to be an expendable commodity, one of the final remaining players drafted by the team's former regime. Beck is a hard worker, but Chad Pennington and Chad Henne appear to be Miami's quarterbacks of the present and future. "It will be hard to get John work," coach Tony Sparano said. "But there's only three quarterbacks right now. That's all we're carrying. With John, he knows his job first and foremost is to compete with Henne. He gets his reps in practice. He'll get some reps in the preseason games, as well."
