The only argument for the QBs is whether or not Matt Moore should be traded or cut and Pat Devlin should be the backup. I don’t think Devlin is ready for that role yet, and the Dolphins have the cap space so keeping Moore around seems to be the likely scenario. Plus, Devlin could always go to the Practice Squad if necessary.
This is one of the Dolphins’ more interesting positions. Miller and Thomas are locks and will see the most playing time. Gillislee hasn’t shown much so far but I think the Dolphins would like to keep him around to see what they have. Thigpen is likely to be the primary punt and kick returner but may also see some snaps on offense as well. Jonas Gray has not really done himself any favors so far this preseason so I think he will likely get the ax.
The first three are obviously locks and will see the majority of the playing time. Quarterback Ryan Tannehill seems to be developing nice chemistry with Wallace and Gibson and he already has a nice rapport with Hartline. After that it gets interesting. Armon Binns would have likely been a lock for one of the spots before he got hurt. Rishard Matthews showed flashes last year and seems to be fully back from his prior injury so I think he is close to a lock. After that, your guess is as good as mine. Marvin McNutt has shown promise but ultimately might have too many drops to make the roster. Chad Bumphis shined early but has tailed off as of late, but I still think the coaches give him a shot.
Losing Dustin Keller obviously throws a huge wrench into the tight end depth chart. A guy like Michael Egnew might have been on the outside looking in prior to that injury, but now it seems he will find himself on the roster. Charles Clay will likely see the majority of the snaps. Dion Sims is primarly a blocking TE but is just a rookie and the Dolphins like what they see in him.
Most of these spots are pretty set in stone already in my opinion. The first five guys will be the starters. Josh Samuda can play both center and guard, and even though he doesn’t play either particularly well he is good depth. Lance Louis is still working back from a torn ACL but he can be a quality addition to the roster. Nate Garner has shown the most versatility of probably anyone on the team and can ultimately play most positions along the line if need be. Dallas Thomas is a rookie (3rd round) and has not looked good this preseason, but the Dolphins need to use him at a position other than LT for him to shine.
Like the offensive line, a lot of these spots are sewn up already. Soliai, Starks, Odrick, Wake, and Vernon are all returning from last year and will see plenty of snaps. Dion Jordan is still not all the way back from a shoulder injury he had this offseason, but the 3rd overall pick will see plenty of time when he is healthy. Vaughn Martin was brought in from San Diego and looks to be the primary backup along the defensive line. Kheeston Randall and Derrick Shelby are both players that have shined in the preseason and look to have ultimately locked up spots. The only other defensive lineman in consideration (to me) is AJ francis but there are too many bodies ahead of him.
Ellerbe, Wheeler, and Misi are clearly the starters. After that, the Dolphins depth is not very good. Spitler and Trusnik are both players that are good special teams contributors and they will be the primary linebacker backups. As for the 6th slot, there are a couple of guys battling for it. I think ultimately second year man Josh Kaddu gets the spot, as he has apparently impressed Head Coach Joe Philbin this offseason. The other players vying for that spot are rookie Jelani Jenkins and Jonathan Freeny.
Again, after Richard Marshall was cut last week it made this list a little easier to come up with. The Dolphins are hoping that rookies Will Davis and Jamar Taylor are going to be able to hold down the nickel and dime corner spots, but first they both need to get healthy.
The first three guys here are pretty evident. As for that 4th spot, that is when it gets hairy. I have Don Jones edging out Kelcie McCray just because I think he has more upside. But I wouldn’t be surprised if the team went the other way either.
After Dan Carpenter was cut, this list was pretty easy to determine. The Dolphins are banking on rookie Caleb Sturgis to be better than Dan Carpenter was last year.
