I'll be upset if this is anything close to their "big" move, obviously, but again i can't stress enough that the "big" move should be for pitching, not for hitting.
TOR Hitting: #23 runs scored, #13 wrc+
TOR Pitching: #22 runs against, #26 fip, #24xfip
And they added a bunch of interesting hitting at the deadline that all projects to be useful along with a bunch of already existing options. And a number of key hitters project to bounce back this year in a significant way as well. There's plenty of reason to be optimistic that this can be an above average offense with elite defense.
But on the pitching side they've lost Kikuchi and haven't replaced him, and arguably overachieved last year already. A big SP add not only is a huge upgrade to the rotation but pushes some other good arms into the pen to help there. There's not much hope to being an above average pitching staff unless all the cards come up right - the old guys stay effective and then a bunch of the big question marks (manoah francis yariel tiedemann) all come up big too.
