The one singular positive thing you can say about Tom Ricketts is that every indication is that he's hands off from day to day decisions. He gives Jed a payroll number, a number we all agree is too low, and then he lets Jed work. This is not an Arte Moreno or Jerry Reinsdorf deal.
So there is little reason to believe the front office is flatly precluded from signing any sort of mega deal. What a mega deal must do though is fit within the team's preexisting budget. We know Tom isn't going to stretch payroll to be "what I originally gave you plus Kyle Tucker." If he were willing to do that Bryce Harper would be our 1st Baseman right now.
Jed has twice in the last three months mentioned how clean the team's books are. So combined with the fact that you logically don't make a deal like this only wanting it to be 1 year, to me it feels obvious the team will try and extend/re-sign Tucker. Maybe they'll fail, Kyle's got agency here, but barring something unforeseen this isn't going to be a "don't let the door hit you in the way out" deal next November. Tucker's not going to get Marcus Stroman'd.
I'll say too, and I've said this several times since the trade, but I think a canary in the coal mine for the prospects of Tucker being here long term is how much 2026 money Jed adds from here. The team as of right now is at about $185M going into next year. Tucker's going to take around $40M. So if you add a Jack Flaherty or Luis Castillo this winter, next year's club would already be at the luxury tax with a hypothetical Tucker extension. That does not feel like a position Jed would want to put himself in 10 months out, so I would read it as a bearish sign on how signable they think Tucker is. Ricketts could hypothetically be planning for a significant payroll spike next year, but back to the article that's not a scenario I would bet on.
