Too soon
Too soon and the least of our concerns (even though I’m sure it was a joke). The Phillies have added precisely one former Nat that anyone thinking dispassionately about the situation cared to retain (Harper), and in that very offseason the Nats added the top FA pitcher that helped them win a WS. I’m FAR more concerned about Rizzo improving his drafting record over the next five to seven years (assuming he’s still in his position) than that issue. If the Philles want to keep giving players massive contracts that stretch into their their late 30s, they should feel free to do so. It’s a spectacularly cost inefficient way to run a team that’s going to inevitably backfire. I suspect by the time Crews is a FA and the Harper and Turner contracts are albatrosses, they’ll have pivoted away from that type of team construction anyway.
