The Dolphins needed a veteran running back, a playmaker and a spark to the offense. The team handled all three by trading for RB Reggie Bush. While he has yet to live up to his potential, Bush certainly improves an offense that ranked 30th in the league in scoring last season. Expect Bush to be used as a runner and receiver, and involved in many screen plays, but rookie Daniel Thomas could still be the one to carry the workload in the backfield. Head coach Tony Sparano knows what he is getting, as he is a close friend of Bush's former head coach, Sean Payton. We hear Bush was third or fourth on the team's RB wish list, likely behind DeAngelo Williams and Ahmad Bradshaw (both of whom became too expensive), but just ahead of Darren Sproles, who signed with the Saints. Sproles might have better numbers than Bush, but Bush certainly brings the excitement factor that Dolphins owner Stephen Ross desires.
