Dolphins' Coach Tony Sparano says that the team may add more players to their roster before the season begins, according to South Florida Sun-Sentinel. Front office officials Bill Parcells and Jeff Ireland were reportedly busy working the phones during Tuesday's practice. "We need to be active," said Sparano, whose team presently has 72 players on the training camp roster. "It all depends on the players that are out there, and maybe what our needs are."
