I think I might be more concerned about the pitching than the lineup, as far as the biggest hurdles to competing in 2025. There are a lot of interesting/useful pieces for the lineup. A few smart additions could make it decent, in similar ways to the way the Rays/As/Giants have pieced together boring but slightly above average lineups in recent years.
The Jays have three pitchers who are locked into rotation spots next year, and they might not be good at all:
Gausman's stuff has backed up to the point where it's below average (95 Stuff+), and he has an xERA over 5 in a full season of work so far.
Berrios has been throwing slop all year, and looks like a fringe MLB starter.
And then Bassitt is Bassitt. Lock in the 2-3 WAR, because he is a machine.
