I believe there's a good chance the Jays see themselves in a league below the Yankees, Astros, Dodgers, Mets and even the Braves (and probably the Padres now). They'd have to mortgage all the future to try and jump up into that level (and still may fall short) would still have to beat them.
I suspect their plan is to simply strengthen the team without shooting themselves in the foot, get into the playoffs and hope you're on a heater at the right time so they have a chance to be the Braves and Nationals of 2019 and 2021.
I respect that evaluation and decision personally.
