A few games are fixed, refs told by NFL to favor a team, the players not involved. A few players collude to lose a game sometimes I’m sure.
These days QBs and most players make so much money they do not need to fix a game.
The “Vegas fixes everything from a secret room” crap is ridiculous.
The “NFL is entertainment like wrestling” so they can fix games argument is nonsense, give me a break.
Basically this, only thing I’d say is I don’t think refs outright say to the nfl to favor a team.
It’s more like “watch for XYZ” knowing what that means or assigning refs that will watch for XYZ. Stern used to be the king of this in his prike obviously
