Story can opt out after 2025 season. Sox can force to negate the opt out by picking up Story's 2028 option.
I doubt Story opts out and I also doubt that the Sox would pick up his 2028 option.
It's time to trade him this winter regardless of what he does, UNLESS BREGMAN also opts out.
Under that scenario, we keep Story at short and have Mayer play 3B.
We can avoid all that by extending Bregman to 2028 with another opt out.
