The only rule that changed was getting rid of the hand-touch takedown, where a hand touching from a rear standing position (which this was not) was the only situation where no reaction time was given. There has been no change to the rule for all other takedowns needing to be “beyond reaction time,” even though it seems to be extended this year. I know there have been a few other controversial ones so far this year, but most of the others were debatable , this one was clear as day. Even most PSU fans I’ve seen are saying it should have been a TD, and I have not seen a single non-PSU fan actually defend it.
