I disagree about the law. I believe the PGA Tour will lose this battle. We will certainly find out who is right about that.
Even if the PGA Tour wins in Court, the long term reality is that if you exclude 20% (soon to be closer to 40%) of the best best players in the world, your tour is at a massive competitive disadvantage.
I guess it will be interesting to see what happens with the USGA and the European Tour. I expect they will have the position that they are supporters of golf -- not a particular random Florida corporation. I bet that view will prevail long term too. I expect you will see Na at both Brookline and St. Andrews. And that you will also see many on this list in the Scottish Open.
I was very confused to read above "No one cares about golf being played in Saudi Arabia." I checked again and, indeed, for the most part, these events will be right here in the USA. I'm looking forward to going to a couple later this year.
