The only issue with that plan is that it would mean Springer would be the only OF on the roster beyond 2023 as Gurriel, Conforto, KK, and Merrifield (if he counts as one) would all be free agents in that scenario. I guess you could offer more than one year to KK, but not sure that's the best idea for a 1-2 WAR player in his mid 30's whose value is entirely defense.
As much as I would dread what a Nimmo contract would look like, right now he probably makes the most sense for the Jays if the intention is to win within the next 3 years. There doesn't seem to be any traction with a Vlad/Bo extension, and this winter's FA market is probably dissuading them from signing anything now. Nimmo maximizes 2023-25 wins more than anyone else realistically available unless the Jays want to sign Correa, which I don't see happening. One year stopgaps would make sense if they want to spend a ton to extend Vlad and Bo right now, but if that's not happening and if they have a feeling it may not happen at all, then spending big on Nimmo might actually be reasonable. You're not getting this type of window again for a while. I'm not saying I want them to sign Nimmo, just that you could argue it makes the most sense for where the team is.
