It's not bad luck that Toronto lost. It's the absence of good luck.
Every roster except maybe Atlanta is sub-optimal/flawed.
The Diamondbacks pitching staff is paper thin with an ace, an SP 2/3, two good relievers, and a bunch of trash
The Dodgers' only good/healthy starter is SP is Bobby Miller
The Twins offense is Royce Lewis and a bunch of league average guys
The Phillies can't defend, and their bullpen is basically all guys who were gas cans 4 months ago
The only starter the Astros have who looked anything like an SP1 or 2 this year is Framber Valdez
The Orioles pitching staff is paper thin without Bautista
Unless Atlanta wins, one of these teams is going to catch a break, get some lightning in a bottle performances, and overcome glaring weakness to win a WS. It happens most years, because the champion is rarely a 105-win powerhouse with no flaws.
