I was for moving Devers to 1B many years ago. I guess you can say I lived with it, but I'd have moved him day one (okay, after some practice), if I was the manager/GM.
Contreras will probably be in BOS for 3 years, since his 2028 option has a $5M buyout, so 1B look out for a Suarez move. I suppose Suarez can DH year 3, as Yoshida is out by then, but that's 2 years od bad and further declining D at 3B. It's not ideal, but we need the bat, and I think the left-side infield defense will be way better, so maybe we cancel out the bad 3B defense.
Paredes is my first choice.
