Matz is probably injured, maybe serious, maybe not, but I suspect some type of injury. The guy has never struggled in his pro career, whether it be major or minor league. Thats a completely different case than Harvey who has had multiple serious injuries the last few years, and has seen his performance, stuff dip once he returned. If Matz is healthy, he's in the rotation. This is kind of the case for a few of these guys. The same applies for Wheeler, and then I guess you could argue for rotation spots with Gsellman, Lugo, Harvey. Thats why I keep saying that the Mets have no need for another Bartolo Colon. If our pitchers are fit, we are accepting worse performance to have a Colon type in the rotation just because a guy hasn't been under the medical care of Mets doctors. Our players are not fragile, its how the Mets deal with these guys, the team is the problem, not the players. Those new pitchers would probably get injured, as well, although Colon might not be the best example for that as how he pitches kind of works against getting injuries. The Mets approach to how they work with pitchers who have good stuff, mainly Warthen getting them to throw harder and with more movement, and then how they manage injuries has often been the biggest problem.
If its a difference maker, like Ohtani, thats a different story. You can always improve every part of your team, but if this team has success, its going to be because our SP's somehow stay healthy, the odds should be in our favor after two seasons where they didn't. Don't try to mess with that, it would take years to successfully change around the team's identity. No turning back now, just gotta hope it works out.
