We can quibble about whether Jeimer is the 4-win player he was in 2020-21, or whether he's worth the 3 wins he is projected for next year by ZIPs. But if we think Jeimer is worth at least 2 wins, which I believe, then he would definitely be worth the $7 million or so he'd've made through arb. And if he's not worth at least two wins, then why would we want him out there at any price? Why bother handing him the job if only he takes the pay cut? Might as well just boot him, change the locks behind him, and hold a waiver wire sweepstakes.
The only way I could accept a justification for their lowball offer to Jeimer is if the Tigers decided they simply don't care what they get out of third base next season, because they don't expect to win in any event, and whoever ends up there is just a placeholder for the chicken that hasn't hatched yet anyway. If that's the explicit strategy, OK, fine, I get it. Then any warm body at third will do in 2023.
However, if they were thinking of taking a real shot at recovering whatever the post-May-8-2021 magic was, which is not a crazy unthinkable idea, then they need at least a 2-win guy at third, which is worth more than $7 million, and my opinion is that Jeimer has at least a 50-50 shot of exceeding that with whoever he ends up playing for.
