One way would be when Finchem was asked if the USGA did go thru with the ban and instead and answering with a we will deal with that when it happens, he could have unequivocally stated that, while the PGA disagree with the ban, the USGA and the R&A are the bodies that define the rules of golf and the PGA will abide by their decisions.
Instead he went on his diatribe of how this is a disagreement among friends ... blah blah blah.
How is that flexing muscle?
If he was a true politician, he would have just lied and then changed his mind later.
This is an open discussion period - everyone can give their views.
Now let's see if the USGA was truthful and really takes all the comments into account.
