Although Gillislee lacks special traits, he couldn't possibly be any worse than Dolphins incumbent backup and second-round flop Daniel Thomas. Gillislee fights hard for yards, has some necessary shake to him, and flashed violence in blitz pickup at Florida. With Lamar Miller having only carried the football 51 career times, Gillislee is a sleeper for rookie-year fantasy value.

The 106th overall pick, Sims was primarily used as a blocker at Michigan State, but has slimmed down and is a natural pass catcher, even if he offers no explosive traits with the football in his hands. The Fins seem to believe Sims can grow into an Alge Crumpler type. He's expected to play significant snaps as a rookie behind blocking-deficient starter Dustin Keller.

A 2012 sixth-rounder, McNutt couldn't make it past final cuts before being promoted from the practice squad for four games late in the season. McNutt has 4.50 wheels to go along with a 6-foot-3, 216-pound frame, but has the makings of a career special teamer/practice squader.

A 2012 undrafted free agent out of USC and then Richmond, Corp is now with his third NFL organization. He'll compete with Pat Devlin for the No. 3 job.

Grimes isn't putting a percentage on his recovery, but says he's "feeling good" and "being smart" in his rehab. Grimes will be 364 days removed from his injury when the Dolphins take on the Browns in Week 1.

"I'm good and ready to go," Clay said Tuesday. Clay should enter the season as the Dolphins' No. 2 pass-catching tight end behind Dustin Keller. Fourth-round pick Dion Sims is primarily a blocker.

"I'm trying to get bigger and faster, improve my explosiveness so I can break more tackles, make guys miss," Miller said Tuesday. "Trying to become a great back in this league." They're lofty goals, but everyone besides Daniel Thomas believes Miller will get a chance to meet them as the Dolphins' starting back. Miller has exciting talent, but the Dolphins are taking a bit of a risk by putting so many eggs in the basket of a back with just 51 career carries. Miller should be treated as an RB2 in fantasy drafts.
