Mets offseason needs and players they must target to contend

Middle Infield
The Mets have a middle infield duo that showed a degree of promise during the final two months of last season.
Amed Rosario and Jeff McNeil both performed very well and left Mets fans hopeful for the future. While this is probably with good reason, the Mets front office must be proactive and pursue backup plans.
The Mets can take a look at Jed Lowrie, Daniel Descalso, or Josh Harrison. There may be more tempting options such as D.J. LeMahieu, but free agents such as him will likely want an assured starting spot.
In the best case scenario, the Mets can add one of these players for depth, which is always necessary. The worst case is that one of these potential signings becomes a starter.
Adam Jones OF
Adam Jones is 33 years old and most importantly would stabilize the outfield by providing competent center field play.
He may not have the range he once did, but it is preferable to having corner outfielders play the position.
Jones can still provide a bit of power as well and would come at a reduced price due to the heavy pursuit of other outfielders such as Bryce Harper and A.J. Pollock. Is he the best fit? Probably not. As a right-handed option with some pop, he’s worth exploring.
