It's what they do. Sign mediocre or worse vet and block young player already in TC system. Play vet and continue to play vet despite it being obvious said vet is beyond terrible and done as a MLB player.
Repeat next year.
I don't think this FO has ever worried about a FA signing blocking a prospect. Especially if they are 80+ games into the year and that FA has proven to be terrible.
Any position player FA signings would be low rent leftovers after teams with money are done signing FA's. No thanks rather see what players already in the organization have/don't have to offer.
