Josh Bell was as bad as, if not worse than Vaughn last year. He's 32 and hasn't been good since 2022. There's no upside here.
Justin Turner is 40 and only played first base regularly after he was traded to Boston. I'm not counting on a 40 year old to not fall off a cliff, especially on this team, and double especially when the "upside" is 1.5 bWAR.
Mark Canha is 36 and was basically the same offensively as Vaughn. He is not an upgrade, especially at his age.
Rizzo is 35, was worse than Vaughn, and couldn't stay on the field for the last 2 years. He's not an upgrade on anyone at this point in his career.
Solano is 37 and only played in 96 games last year. He's probably not a full time player anymore, and he's never been a full time first baseman. At best, you'd still need someone else there for more than half the time, and at worst he falls off a cliff due to his age.
Abraham Toro has only played at first in 15 of his 311 career games, and he was a worse hitter than Vaughn last year. I don't care how much cheaper he might be, he'd absolutely be a downgrade especially at a position he barely plays. He's probably the worst option in a field of bad options.
Carlos Santana is the only one with solid production, but he's also going to be 39 years old when the season starts. It's likely he falls off a cliff, and then you're paying a guy who hits like Vaughn or worse as much as or more than you'd pay Vaughn. No thanks.
Yeah, I'll stand by what I said.
