Granderson is dead weight. He is holding this team back. Conforto and Lagares make for a great platoon in CF, with Conforto splitting starts vs LHP with Bruce in RF.
It was pretty clear that Bruce shouldn't have been the guy being shopped in the offseason. Granderson could've fetched more value then, as teams reportedly were more interested. Sandy should've made that deal.
Granderson might still get us some bullpen help. We can wait a couple of months and see how things shake out. We might have other needs as the season wears on. Perhaps a SP even. But, it will be harder to get value if Granderson is on the bench where he belongs right now. I would just pull the trigger early. Get some BP help. With this staff, if the Mets get a 5th reliable guy to go with Blevins, Salas, Reed, and Familia, the BP will be in great shape.
I also would stop worrying about who will hit leadoff. It does not matter much. The Mets' lineup is loaded if Conforto starts in CF. The team has hitters. Just roll them out there and let them do what they do. Conforto could actually hit lead off if need be. If Reyes does not get it together, I would consider giving 3B to someone else. Flores would be an option, he is just so bad there defensively. If Wright were to ever come back, this team would be absolutely loaded.
Duda needs to play more regularly at 1B. I would still find ways to get Flores in the lineup vs. LHP. Just not always at the expense of Duda. Let Flores get a few starts at 2B as well. But, Flores really has no business in the lineup vs. RHP. Especially when he is placed in the cleanup spot and left in there as the guy hitting behind Cespedes, but vs. RHP late in the game. It just doesn't work. TC will need to stop using his bench guy who can come in for Flores as pinch hitters in other spots when he has Flores at clean up.
Later in the season, if it becomes clear that Wright will not return at all, and Reyes continues to struggle, I would think about moving Cabrera or Walker to 3B, if they can play the position, and bringing up Rosario to play SS.
A long way to go. A lot can still happen. Injuries can reshape how things work out. We need all of these guys as depth. But, the one guy who can go and it not kill the team, even if injuries happen, is Granderson. Go ahead and move him.
