#3 More Bats
The Mets have done a lot of good work improving a lineup which finished 27th in runs per game in 2021. Starling Marte, Eduardo Escobar, and Mark Canha will provide a lot of much needed power and speed to a lineup which was sorely lacking in those areas.
As it stands currently, the lineup looks solid. However, there is room for improvement. Kris Bryant is still a free agent and vastly improves the lineup. This likely means Jeff McNeil is trade bait as they'd plug Eduardo Escobar in at second base with Bryant at third.
Signing Bryant would be nice, but it isn't necessarily a necessity. The Mets lineup should be good enough as is to win some games, especially if they address the pitching even more than they have. But, you can never have enough depth.
If the Mets opt to not sign Bryant, they should sign a bunch of depth guys. Jonathan Villar gave the Mets more than they ever could have expected this season. Maybe he'll come back in a bench role. Brad Miller hit 20 home runs while playing a lot off the bench. Maybe he'll sign with the Mets.
After the Mets had to run a lineup with an outfield of guys Cameron Maybin, Johneshwy Fargas, and Khalil Lee at one point because of injury, they should know to get as much depth as possible.
