The Dolphins pulled off a surprise Tuesday morning in dumping running back Jay Ajayi to Philadelphia for a fourth-round pick. Yes, dumping. This wasn’t a value trade. This was a regime pointing the finger at Ajayi for underperforming from their view this season. Adam Gase mentioned last Friday he was, “pissed” about the “best players” on offense being at the center of the offense’s problems. He didn’t name names. He just evidently got rid of one of them. In doing so, he said just was a problem the locker room had become inside the Dolphins this year for him. Ajayi was the player this offense was built around last year and, again, in a suffering way this year. But to get only a fourth-round pick for him? That’s not value. That’s a dump. And now? The Dolphins have Damian Williams and Kenyan Drake as running backs. William has 12 carries for 32 yards (2.7 average) this year. Drake has 10 carries for 25 yards (2.5 average) — and six of the carries came in mop-up duty of Thursday’s 40-0 loss in Baltimore. Also, Tuesday at 4 p.m. becomes the next milestone in the Jarvis Landry saga for the Dolphins. Namely, will Landry follow Ajayi out the door before the trade deadline passes? Is there any reason to keep Landry, who probably won’t be here next year, if you’re already trading off important parts to the offense? There are good reasons to trade Landry – and good reasons not to trade him. The pivotal issue is his contract is up at this season’s end and he can be a free agent.
