R – Denotes rookie

QUARTERBACK

Automatics: Ryan Tannehill (R), Matt Moore

Very likely: David Garrard

Competing for practice squad job: Pat Devlin

Comment: The starting job seems likely to come down to Garrard and Moore, though Tannehill will have a chance to compete. If Garrard bombs in camp and Tannehill shines, Garrard (due $3.3 million) could be at risk. But considering many consider Garrard to be the slight front-runner to start, that’s difficult to envision.

RUNNING BACKS

Automatics: Reggie Bush, Daniel Thomas, Lamar Miller

Competing for two spots: Steve Slaton, Marcus Thigpen, Jonas Gray (R) and fullbacks Jerome Messam (R), Jorvorskie Lane (R) and Ryan Mahafee

Comment: Bush closed 2011 with four consecutive 100-yard games before missing the finale and hopes to duplicate last year’s 5.0 per carry average. But the Dolphins might throw more, and Bush – well suited for the West Coast offense – will be lined up at times at receiver. Bush said the speedy Miller is ready to contribute immediately. And Thomas, who has much to prove after an injury-plagued rookie season, said the Dolphins’ new zone blocking scheme suits his skills. Thigpen needs to impress on special teams to have any shot of sticking. Miami would like to keep a fullback and hopes one of the three seizes the job.

RECEIVER

Automatics: Brian Hartline, Davone Bess

Good chance to stick: Chad Johnson and Legedu Naanee

Competing for two or three spots: Roberto Wallace, Clyde Gates, Marlon Moore, Julius Pruitt, Chris Hogan, B.J. Cunningham (R), Rishard Matthews (R), Jeff Fuller (R)

Comment: The Dolphins say Johnson must earn a roster spot, but he looked good in minicamp and still might be Miami’s most physically gifted receiver. Naanee had a solid offseason and has a good shot to be in the top-four rotation. And “a guy people are sleeping on, who’s going to be around here, is Julius Pruitt,” Hartline said. “And Roberto is doing a great job as well.” Still, it would be a bit surprising if the Dolphins give up on Gates so soon, considering general manager Jeff Ireland has spoken so highly of him and he has value as a kickoff returner.

TIGHT END

Automatics: Anthony Fasano, Charles Clay, Michael Egnew

Competing for any remain roster spots: Jeron Mastrud, Will Yeatman, Les Brown

Comment: Joe Philbin’s Packers kept five tight ends last year, but Mastrud and Yeatman must show more in camp to justify roster spots. The tight ends will be a key part of the passing game, and offensive coordinator Mike Sherman has crafted packages to use Fasano, Clay and Egnew together on occasion.

OFFENSIVE LINE

Automatics: Tackles Jake Long and Jonathan Martin (R), guard Richie Incognito, center Mike Pouncey

Very likely to stick: guard/tackle Artis Hicks, tackle Lydon Murtha, guard Eric Steinbach (if healthy).

Competing for two or three spots: guards John Jerry, Ray Feinga and Derek Dennis (R); guard/center Ryan Cook and Josh Samuda (R); tackles Will Barker, Dustin Waldron (R) and Andrew McDonald and guard/tackle Nate Garner

Comment: The Dolphins hope Martin, their second-round pick, can win the right tackle job. Steinbach, signed Thursday, is apparently healthy after last year’s back surgery and has a good chance to beat out Hicks and Jerry if he returns to past form. Samuda got some work at center this offseason and would be a cheaper alternative to Cook, who’s due $1 million if makes the team. Garner’s $1.4 million salary could put him at risk.
