Lex Hilliard has managed to stay on Miami's roster for the last three years, but his time with team may expire shortly.
He is a restricted free agent in March, and the Dolphins don't have much incentive to bring him back. Hilliard turns 28 in July, and while he has performed well on special teams, he hasn't been effective with the ball in his hands, and the team can easily replace him with a younger back.
The Dolphins gave Hilliard a chance to establish himself as a short-yardage back, but he was eventually replaced by Steve Slaton. It doesn't seem like the organization has too much confidence in Hilliard anymore.
