Koepka has been vocal about pace of play violations and the pga not enforcing the rule. Perhaps he considers that cheating.
And the secret colusion of leaving your ball down on the green as a backstop for another player. Back when that was happening, that was happening quite often given that I was seeing it multiple times on the smaller sample size of what was shown on tv. Mickelson claimed that the Lexi type move of placing her ball down a bit 'incorrectly' on the green happens often on the PGA (imo that appeared intentional). Perhaps Koepka considers these types of things as cheating.
I listened to this today, and wowsers, does he every speak the truth. What I found really interesting is that he literally laid out 4 times that he saw Reed improving his lie. He also mentioned that this is rare behavior, but that every generation has someone that does this sort of thing. I suppose we are just in the Reed era right now. He was also very forthcoming that he believed the punishment did not come close to fitting the "crime".
They should report what they see.
But who ever thought TV (anything) was fair and square. Peter had a great job with a really crummy organization. I don't blame him for trying to do what he's instructed. He did what he could on a couple fronts - obviously given what happened last year.
