I totally agree.
Yellow card and cut the purse. That would get the fighter's attention.
I normally don't mind Wiman, but you can't have fighters totally ignoring a referee warning during a fight, as we saw in this one.
I think that we have been seeing more fence grabs, and more shorts grabs in the last couple of events than ever before.
If something is going to be defined as against the rules, then it needs to be enforced. Otherwise, why bother making it a rule?
That said, I think that this was great free event.
