When you scan the roster of the 2012 Mets, there are only a handful you can justify returning, and only fewer they should bring back. The following are the Mets you know will be back next year:

JOHAN SANTANA: I’d love for them to find a taker of his $25.5 million contract, but you know that’s not going to happen. Santana will go down as one of the Mets’ worst trades for what they got from him after signing him to a long-term deal. Never mind the prospects for they didn’t amount to much, but the salary became an anchor that dragged down the franchise, especially considering how often he was injured. The Twins’ asking price forced the Yankees and Red Sox to pull out, essentially leaving the Mets to bid against themselves, both in prospects and salary. He’s back because he can’t be unloaded. That’s the only reason.

R.A. DICKEY: I don’t know what it will take to bring Dickey back, but the Mets can always pick up his 2013 option and continue to muddle through negotiations. My confidence level of GM Sandy Alderson reaching a contract extension is low. Whether the Mets bring Dickey back to continue negotiations or to trade him is uncertain, but he’ll be on the Opening Day roster.

JON NIESE: He’s signed long-term, which is a smart signing by the Alderson administration. Young, left-handed arms are at a premium. The Mets could get a lot for him, but his real value is in building around him.

MATT HARVEY: He made such a good first impression that he’s already penciled into the Mets’ 2013 rotation, and hopefully will stay there for years to come. When teams call the Mets to talk trade they invariably ask about Harvey and are properly turned down.

DILLON GEE: The returns on Gee’s surgery are good and he’s expected to be ready for spring training. The Mets could find a veteran capable of giving them Gee’s production, but not at his salary. Gee has been a find, and if healthy, he’ll be a reliable No. 5 starter.BOBBY PARNELL: Parnell did not grasp the opportunity to be the Mets’ closer and struggled as the set-up option. However, when Frank Francisco went down and Jon Rauch struggled, Parnell showed improvement in the second half. Parnell’s fastball is overpowering and he’s continued to develop his secondary pitches. That he’s healthy and can throw a ball through a wall would make him attractive in the trade market. Considering his age, that’s also why the Mets should continue in developing him.

ROBERT CARSON/JOSH EDGIN: Opportunities are found in the strangest places, and Edgin and Carson found theirs with Tim Byrdak’s injury. The Mets blew out Byrdak’s arm, and desperate for lefty help in the bullpen, dipped into their minor league system for these two. Both struggled at times, but also showed glimpses of what they could bring to the table. Unless the Mets get lucky this winter, they’ll go into spring training with these two lefties in the bullpen.

 FRANK FRANCISCO: He has another year on his contract – a foolish deal, agreed – which is why he’ll be in Port St. Lucie. But, if the Mets can make a deal for him they should as he really doesn’t add much to their porous bullpen.

JOSH THOLE: Both Thole’s defense and offense have regressed. Alderson seems pleased with the way he handles the staff, but he does get healthy. In a perfect world, the Mets would trade for, or develop, another catcher, but won’t as they have little to trade and little in the minor leagues. Thole comes back because the Mets have too many other priorities to address instead of their catching.

IKE DAVIS: Don’t listen to the trade rumors. He’s not going any where. A team void of power and is pinching pennies isn’t about to deal their 32-homer hitting first baseman. Not at his salary. Unless the Mets can get a boatload in return, what’s the incentive in dealing him? And, with Lucas Duda a question, why would they take that risk?

DANIEL MURPHY:  It’s too bad Murphy doesn’t hit for power otherwise he’d be a keeper. Murphy played better at second to the point where the Mets don’t have a red flag waving at the position anymore. As with Thole, he’s good enough to stay at his position while the Mets address other issues.

RUBEN TEJADA: Tejada more than adequately replaced Jose Reyes and should be here for years. If he has another year like he had in 2012, the Mets should think of an extension to keep him away from arbitration and free-agency. Will he ever be as good as Reyes? Probably not, but he’s more than good enough.

DAVID WRIGHT: I don’t see him going anywhere. As with Dickey, if the Mets don’t get anything done they’ll pick up his option and see what they can get in the trade market. It’s harder to trade a player these days during the winter because teams have the free-agent option to improve. I believe the Mets will eventually work out a deal with Wright, who said he wants to be like Chipper Jones and play his entire career with the same team.

JASON BAY: Like Santana, Bay is back because they can’t deal that contract. His value to the Mets is staying healthy and having a strong first half so the team might be able to deal him. But, after doing nothing the previous three years, that’s not likely.

SCOTT HAIRSTON:  It is hard to say good-bye to 20 homers, but that’s what I can see happening with Hairston, who’ll likely get a better offer in the free-agent market while the Mets wait things out. Hairston, despite being a role player, what the Mets’ most productive outfielder. Whether as a starter or coming off the bench, there should be a place for him with the Mets.

LUCAS DUDA: He’s back not based on 2012 production but potential. Duda had a rough season, but he’s strong as a bull and the Mets need the power. Yes, he’s a butcher in right field, but I’d consider flipping him with Bay and playing him in left field.
