This was simply the case of a high profile standalone game where “the office” saw something that put KC behind and made the call because it was technically correct. The on-field official was put in a bind because now he knows they missed the infraction. Since the next play hasn’t started he has to either 1) ignore that he knows it was a foul by following the rules, or 2) break the rules and use assistance on a play that doesn’t allow assistance. The bet didn’t play a part at all. Bias and opportunity did.
Bigger point to this current conversation, bringing up Jaymo’s name is just reckless and inappropriate. That is how baseless rumors start. Please stop.
