Dolphins Beat: Arian Foster, Jay Ajayi 'both should get plenty of carries'

In Arian Foster, the Dolphins believe they are getting the player far closer to the one who averaged 4.8 yards and ran for 1246 yards in 2014 than the one limited to 2.6 per carry in four games last season before a ruptured Achilles.

Foster, who ranks 10th among active backs in career rushing yards, is only 29. But durability has been an issue in recent years. He missed 23 of a possible 48 games, due largely to a 2013 back injury and last year's Achilles' injury, which was sustained in late October against Miami.

But Foster impressed the Dolphins in a workout today -- "looked good," one source said -- and the Dolphins wanted to move quickly before he had a chance to board a flight and work out for Detroit.

Foster will compete with Jay Ajayi for the starting job. But regardless of who starts, both should get plenty of carries, presuming Foster stays healthy. Remember, Adam Gase has raved about Ajayi throughout the offseason program, though he has dropped a few passes.

We're anticipating a timeshare for now, with Foster having the better chance to earn a lion's share of touches (if healthy). He also has the better chance of going down with a season-ending or long-term injury.
