“I would tell you I’ve nver been in a meeting where I’ve said to [offensive coordinator] Bill [Lazor] or [running backs coach] Jeff Nixon or the offensive line coaches have said ‘Lamar can’t carry the ball 20 times a game. He can’t do it,’” Dolphins coach Joe Philbin said, per
James Walker of ESPN.com. “I’ve never heard that. That’s never come out of my mouth.”
Moving forward, Ajayi was one of the most prolific backs in the entire country. He's under team control at an almost nonexistent salary; none of his cap hits so much as reach
$800,000 during his rookie deal. If Ajayi flashes potential in 2015, the Dolphins might be smart to allow Miller to hit free agency and hand over the reins to the youngster.
"In Miller’s case, the Dolphins might have a possible replacement in Jay Ajayi—every top Dolphins executive keeps calling Ajayi a three-down back—but nobody has seen nearly enough of the rookie to know that for sure," Jackson wrote.
We're getting way ahead of ourselves here, but running back is a fungible position. Players hop in and out of prominence each year, and Miller's own career arc shows that. After being nearly anonymous his first two seasons, he broke out in 2014. Miami would be smart to hold off on a deal until the running back hierarchy begins playing itself out.
