Vargas will never get beyond solid starter, IMO. Like, in the next 4 years, if he has a primary position, maybe he has a 3-4 WAR year, or two. The end. I believe the Sox will be pushing the upper 70s in wins this year, and be competing for the last wild card spot in 27, so no, don't trade him. He's a place-holder. But Bonemer, Carlson, 2026 1st rounder will be moving him off of his spot in the coming years. I really don't think the Sox are building for a window. This is the "steady flow" of talent Hahn always dreamed of. If they can draft and develop guys like Bonemer, Vargas will become expendable.
I don't think the Sox should trade Vargas. I think he should be a Sox regular (if he earns it) until he's pushed out. I'm just saying that of course he should be getting interest because I think he has one more plateau to reach as a hitter.
