It appears he won't receive one anytime in the future, either.
According to Ian Rapoport of NFL Network (via Dan Hanzus), Bush is unlikely to re-sign with the Dolphins.
Bush's representatives met with Dolphins brass earlier this week to get a feel of the situation. Bush wants to remain in Miami, but he also wants a competitive multi-year deal. The two sides aren't matched up.
All signs point to the Dolphins going in a different direction at running back.
Right now, that means we'll see more of third-year back Daniel Thomas and second-year back Lamar Miller.
Thomas was largely unimpressive in his action last season, averaging 3.6 yards per carry and missing four games with injuries, including multiple concussions. His 3.54 YPA over the past two seasons is the lowest for any back with at least 250 carries.
Who should earn more carries in 2013?
Miller did not earn a heavy workload last year, which could be due in part to his strikingly similar skill set to Bush's. That skill set could help the Dolphins transition into life without Bush. The problem is, the Dolphins don't really know what they have in Miller because he didn't receive much playing time.
That being said, the Dolphins could be in the market for another running back for depth. They have used a second- and fourth-round pick on running backs in the past two seasons, so while they could address the position with one of their five picks in the first three rounds or 10 picks overall, it would be the third time they've drafted a back in as many years.
Perhaps they'll search for what they were hoping to get in Bush: a talented, veteran free-agent running back who may come on the cheap. Felix Jones and Ahmad Bradshaw come to mind as elusive, explosive free-agent running backs in a similar mold to Bush.
The Dolphins have options at running back, but in the 2013 season, Bush will not be one of them.
