The Miami Dolphins roster is a fluid situation, and will likely remain that way for weeks, if not months.
It has become clear the Dolphins will churn the bottom of the roster all season searching for the right pieces.
That process began on Saturday when the team claimed four players, including former practice squad receiver Anthony Armstrong, whose ability to produce big plays should help this limited receiving corp.
Here's a look at Miami's 53-man roster heading into the Sept. 9 regular season opener against the Houston Texans.
Quarterback - Ryan Tannehill (R), Matt MooreDavid Garrard, Pat Devlin
There is a slim chance the Dolphins keep four quarterbacks on the 53-man roster, so that means someone is being traded (Moore), demoted (Devlin), released or placed on injured reserve (Garrard). My vote is that Garrard will be placed on injured reserve considering the NFL's new rules would allow him to return to the active roster later this season.
Tailback Reggie BushDaniel ThomasLamar Miller (R), Marcus Thigpen (R)
This is Miami's deepest unit, and all four backs bring something different to the table. Bush should excel in a zone blocking scheme. Thomas is a big physical back who appears to be running with power now, his second season in the NFL. Miller is a stretch the field type option who must get used to a zone blocking scheme, and Thigpen is a pour man's Dave Meggett. he'll likely serve as the backup slot receiver and kickoff returner.
Fullback - Jorvorskie Lane (R)
Lane was one of the most pleasant surprises of training camp. He's a solid lead blocks with decent hands, and the ability to gain short yardage on tough, physical runs.
Receivers - Davone BessBrian HartlineLegedu Naanee, Anthony Armstrong, Marlon Moore, Rishard Matthews (R)
Getting Hartline back from his calf injury, and the addition of Armstrong should help this unit. But they are still one of the weakest receiving corps in the NFL. Someone will need to elevate their game drastically to keep this offense from dwelling at the bottom third of the NFL. Its likely that Miami will continue to upgrade this unit throughout the season. Matthews could easily be snuck onto the practice squad.
Tight end - Anthony FasanoCharles ClayMichael Egnew (R), Jeron Mastrud
Fasano and Clay are the two workhorses, but there is little quality behind the pair right now. Egnew, Miami's third-round pick, is raw and needs time to learn how to become an NFL tight end. Mastrud is a versatile player, but someone who is limited. It's possible he could be churned if the Dolphins find something they like better on the waiver wire.
Offensive tackles - Jake LongJonathan Martin (R), Will Yeatman
Keeping Yeatman was a bold move considering the former tight end is rough around the edges, but the talent is there. He needs time to develop, and that could be done on the practice squad. Long, a four-time Pro Bowler, will need to recover from his MCL sprain to make this offensive line respectable. Martin, a second-round pick, is still working on his transition to the left side.
Offensive guard - Richie IncognitoArtis HicksJohn Jerry, Nate Garner
Hicks is recovering from a neck injury he suffered two weeks ago and should be a solid stopgap, but there's concern about what's behind the two starters. Garner can play every position on the offensive line, but is he a good fit for this zone blocking scheme? And Jerry, who came to camp 360 pounds, has made drastic improvements the past three weeks. But the fundamental issue is that he's proven he can't be trusted.
Centers - Mike Pouncey, Josh Samuda (R)
