You can replace him, of the 2026-27 free agent class he’s the best available outfielder in my opinion and it’s a stretch to assume Cassie or any in house talent will be as good or better. This isn’t Theos farm system. So yes, if they void or plan on voiding his contract and the plan is having 6/9 starting positions players on cost controlled rookie contracts then either extending Tucker or proactively signing, Bo Bichette to offset his loss for example is an unlikely option but one I’d prefer. Much like what Jed tried doing with Bregman and He’ll only be 28 if available.
