Safe to say Rory McIlroy isn’t loving the new Tour Championship rules.

An overhauled scoring system called “Starting Strokes” will give FedEx Cup points leaders an advantage to begin play, with Justin Thomas beginning the four-day tournament that begins Thursday at 10-under par. Patrick Cantlay will start at 8-under with Brooks Koepka one stroke behind him and Patrick Reed one behind Koepka. McIlory will be at 5-under, and the rest of the 30-golfer field will be playing even more catch-up.

The system was put in place to make things easier for viewers to understand after Tiger Woods won the tournament in 2018, but Justin Rose took home the FedEx Cup victory as the overall points leader.

“You can shoot the best score of the week and not win the tournament,” McIlory told reporters. “If that happens to someone, it’s going to be hard for them to wrap their head around.”

Especially considering the prize money for the 2019 Tour Championship got a big boost and is up to $15 million for the winner, plus a five-year exemption.

“I get it from a fan experience point of view, I get it from giving guys that have played better throughout the year an advantage, but I don’t know — come back to me on Monday and I’ll tell you if it has worked,” McIlory said

“We had breakfast with some of the sponsors and what I said to them was if the PGA Tour is trying to do this ‘season of championships,’ which starts with the Players in March, then goes through the four majors and culminates with the FedEx Cup at the end, if the FedEx Cup really wants to have this legacy in the game like some of these other championships, is people starting the tournament on different numbers the best way to do it?” McIlroy said.

The adjusted format would change only two Championship winners in the past 12 years, in 2008 and 2011, but the 2019 version could be over before any drama can even build.

“With this format it has the potential where myself and a couple of guys get hot at the top of the leaderboard and it could be a one-man show,” Thomas said. “But if some of us at the top don’t play well, you legitimately have the chance of 25-28 guys that have a chance to win $15 (million) on Sunday.”
