The Mets have plenty of internal options when it comes to finding a starting third baseman.
Jeff McNeil, J.D. Davis and Jed Lowrie are all capable of handling the position, so it's quite possible Brodie Van Wagenen looks to add an outfielder instead, knowing McNeil can play in either spot.
The other play this offseason is to go heavy at third base options and put McNeil in the outfield, who looked comfortable and played well in left field this past season. I still think he's a second baseman, but that's a different subject for a different day.
