Rory McIlroy's controversial decision leaves PGA Tour 'very concerned'

The PGA Tour must make changes because McIlroy won't face any repercussions for skipping the FedEx St. Jude Championship. As the No. 2 player in the FedEx Cup standings entering the postseason, McIlroy is guaranteed to qualify for the Tour Championship. Before this year, he would've been incentivized to improve his spot in the standings because of the advantage the starting strokes format gave the No. 1 player. That's no longer the case. 

This year, the Tour Championship will operate like every other tournament on the PGA Tour schedule. There will be no starting strokes advantage for the top players, so every player from No. 1 to No. 30 will have an equal chance to win the $10 million prize. 

It doesn't matter where McIlroy resides in the standings. It just matters that he makes it to East Lake Golf Club in Atlanta, and he's already locked up his spot in the season finale. Why spend a week in scorching-hot Memphis when you could stay home and prepare for the tournament that actually matters, right?

The new playoff format will make the Tour Championship more entertaining for fans, but it renders the other two playoff events irrelevant for the PGA Tour's top players. The Tour must make playoff events mandatory to prevent other stars from following McIlroy's lead.
