A lot of the roster that got the Dolphins into this 5-10 mess will be back next season. But decisions await on several veterans as Miami seeks to upgrade at multiple positions.

At least 10 players who have been here for years — such as Paul Soliai — will play Sunday’s finale against the Jets without any idea if it will be their last game in a Dolphins uniform.

The most intriguing questions surround Soliai, Kendall Langford and Vernon Carey. Soliai and Langford want far more money than the Dolphins were willing to offer during negotiations earlier this season. The Dolphins could again use the franchise tag on Soliai, but that would be very costly after paying him $12.4 million this season.

Carey has played decently at right guard, but the Dolphins could opt to go with John Jerry.

Jason Taylor has played well enough to earn another year, but it won’t be surprising if he retires.

Others assuredly won’t be back, including right tackle Marc Colombo.

Here’s a breakdown of the roster heading into the final game against the Jets, who need a win, losses by the Bengals, Titans and either the Broncos or Raiders to make the playoffs:

Quarterbacks

Matt Moore: One year left on contract at $2.5 million. Ranked 11th in NFL in passer rating (89.8). Decent chance he remains the starter initially in 2012 if Fins draft quarterback as expected.

Chad Henne: Free agent. Hasn’t been asked back and will seek chance to start elsewhere.

J.P. Losman: Free agent. Nomadic career likely will continue elsewhere.

Pat Devlin: Dolphins will own his rights if he ends season on 53-man roster, as he is now. Will earn $465,000 if he makes team.

Running backs

Reggie Bush: One year left at $4.5 million. Not only is he ninth in the league in rushing yards (1,086), but his 5.0 average is higher than any of the eight ahead of him.

Daniel Thomas: Three years left on contract. Will earn $522,000 next season. Averaged 4.9 per carry in first two games but has sunk to 3.6 while battling injuries. Must prove himself to new coach.

Steve Slaton: Free agent. Had just 20 offensive snaps.

Lex Hilliard: Free agent. Could return, but not definite. Ranked 16th among all fullbacks by Pro Football Focus. Pretty good on short-yardage runs.

Receivers

Brandon Marshall: Three years left on contract, paying $9.3 million, $9.1 million, $9.1 million. Ranks seventh in league in receptions (77) and yardage (1,177).

Brian Hartline: One year left at $565,000. Several outstanding recent catches enhance chances of returning as starter. Leads Dolphins in average yards per catch (16.2) for third year in a row.

Davone Bess: Two years left on contract, at $2.2 million and $2.6 million. Has been targeted much less than last season, which largely explains drop in catches from 79 to 45.

Clyde Gates: Three years left on contract. Will earn $465,000 in 2012. Caught only two passes and played fewer than 140 snaps on offense but has boosted kickoff-return average to 25.0 (10th among all players with at least 20 returns).

Marlon Moore: One year left. Will earn $490,000. Played only one offensive snap before going on injured reserve.

Roberto Wallace: One year left. Will earn $490,000. Quality special-teams player, but — like Moore — will need to prove worth to new coaching staff.

Julius Pruitt: Restricted free agent. Longer odds than Moore and Wallace.
