Conspiracy on altering states of fighters

Spence did look off in color before the walkout like he just smoked, maybe they can alter fighters states these days with releasing something in the air.. I always had that conspiracy, also increase the performance of the other with another high oxygen, can pump co2 into losing fighters dressing room and o2 in winning.. just a theory but Spence did not look on point so much it raises an eyebrow. I get Crawford is good but how did Spence do so much worse than others? Maybe Crawford elevated his game, perhaps the effects of the accident were brought out more in camp after hard sparring and pushing too hard being weigh drained. Idk just some thoughts..
