I actually think there's a decent probability that things play out the way Joltin Joe has suggested. They trade all the rentals at this deadline because they do want to contend next year. As my good friend jaysblue suggested, if you squint really hard, you could see the Jays add offense (corner OFer, DH, maybe 3rd base), another SPer and some bullpen help via free agency. That coupled with bounce back years from Bo, Gausman, Berrios and hopefully some breakout years from the youngsters and there's a real possibility we can make the playoffs next year.
But - there's also a real possibility that it blows up in their face again and they are big time sellers before the next deadline. Vlad, Bo, Gausman, Bassitt, Berrios, Springer, Varsho, Green, etc. could all be moved (yes, it's unlikely they would ALL go, but they'd all be potentially on the table).
That cookie of potentially contending next year, combined with ownership pressure to keep the dome full to pay for the reno's may ultimately extend our rebuild time as player value will decrease as they inch closer to free agency. That said, in some cases (like Bo and Gausman), their values may not decrease as much if they can rebound next year (v. their current value). If they do pull it together and make the playoffs again in 2025 - perhaps it's all worth it.
