The Nemesis
Semper Tyrannus
Unless the unthinkable happens and the Jays win the Soto lottery, I think Bregman is a nice first piece for Plan B (or realistic, non-Soto plan A). He's not what he was at his 2018-19 peak but the last 3 years he's played most of each season and been good for 20-25 HR, an OPS around or above .800, and solid enough D at 3rd.
That fills an important fielding hole with a guy who has a playable bat. Him and an OF wouldn't necessarily "fix" all the offensive problems, but they'd go a long way to lengthening the lineup so the problems that remain are coverable. Santander would be the ideal. Assuming Teoscar is set on returning to LA then Tyler O'Neill is the best of the otherwise underwhelming set of corner OF fallbacks, but signing him means living with the fact that he is best as the weak side of a platoon because he crushes LHP but is very underwhelming vs RHP.
That means next year's lineup could conceivably be something like
1) Springer (RF)
2) Guerrero (1B)
3) Bichette (SS)
4) Bregman (3B)
5) Santander^/O'Neill (LF)
6) Horwitz (DH)*
7) Kirk (C)
8) Wagner (2B)*
9) Varsho (CF)*
*LH Bat

As much as the Jays keep popping up on lists of teams going after pitching, that's a secondary concern that can be answered from the 2nd or 3rd tier of FA arms or risky upside bets because mostly they need to add a 4/5 and maybe a couple of depth arms that can be ready in case of injury or performance based attrition. And filling out the pen is a fairly low-cost exercise in buying a ton of lottery tickets and using the spring to see which ones pay off because spending "proven closer" money is often foolish and easily destructive.
