I disagree with this.
They inherited an old team that had hung onto competing far too long. The first 3-4 years was spent rebuilding/retooling. The team developed their core tandem of Vlad/Bo and have surrounded them with a lot of young and/or cheap talent:
Manoah
Kirk
Teo (whom they got for free)
Jansen
Moreno
Romano
Espinal (whom they got for free)
That's 5 All Stars, the #1 prospect in baseball and Danny f***ing Jansen (aka 141 wRC+ Danny Jansen) that they have developed and surrounded the 'big 2' with since their debut in 2019. Obviously Moreno is part of the next wave, as is Zulo, Teids, Barriera, Gabby, Juenger, Macko, Barger, Doughty, etc.
There are teams that have 'done it better' than the Jays since 2019 (LA, Cards), but I don't think there are many...
