To be fair, the sound of the impact on the cup was audible and evident. That means there was, in fact, contact to the groin area.
The bs is that the contact wasn’t direct, it was residual contact made by the flat part of the foot-or maybe even a bit of the heel.
Meaning, it didn’t hurt- and certainly not enough to be putting on the act he was trying to put on.
By rule, it warranted a stoppage. But it didn’t warrant a break(time to recover).
