The Mets are expected to turn their attention to "reconfiguring the outfield," and, "adding to the bullpen," as a source recently told me, now that Yoenis Cespedes is back in the fold.
Also, though it's far from a top priority, I expect the Mets to explore finding a new every-day catcher, "specifically a veteran to handle their pitching staff," as a rival team described it.
How do the Mets reconfigure the outfield?
According to multiple reports since early November, the Mets are open to dealing Jay Bruce or Curtis Granderson to eliminate a left-handed bat, open a spot in the outfield and save money on payroll. Alderson has been asked a lot about Michael Conforto, but the Mets are unlikely to deal him because he's got a ton of potential as a hitter, plus he's athletic enough to center field and first base.
The Mets will use next week's MLB Winter Meetings to pin down a deal for Bruce or Granderson. However, because there are several teams in the market for a corner outfielder, I think Alderson could find himself in a situation where he may be able to trade both of these guys, add speed and a reliever and either upgrade at catcher or save money.
