While this is obviously a troll post, I never fully understood how "leagues" could rig the games (except for in reffing)
It would be near impossible to get the players involved without them leaking that they were payed off, and yet losing teams always think this.
Biases do exist on 50/50 calls but besides that it is very hard to rig anything, too many variables in sports like baseball.
For true rigged matches you need 1 on 1 type sports like boxing or tennis
