Rory McIlroy questioned whether LIV Golf players have brought value to their league.

He spoke Wednesday at the BMW Championship.

He was responding to a question about the value they would bring to the PGA Tour if they returned.

LIV Golf's future is uncertain.

Its final event of the year is this week in Indianapolis.

Saudi Arabia's sovereign wealth fund will no longer fund the league.

LIV CEO Scott O'Neil said players would become equity owners under a new plan.

He did not name the lead investor or the size of the investment.

The key players for LIV are Jon Rahm and Bryson DeChambeau.

Both are two-time major champions.

Brooks Koepka returned to the PGA Tour this year under strict penalties.

The tour offered a similar deal to Rahm, DeChambeau, and Cameron Smith.

Scottie Scheffler said LIV has some very good players who would add value to the tour.

He said there should be some penalties for returning.

McIlroy said the road back would be tough.

He noted that any future offer likely would not be as good as Koepka's.

LIV also faces two lawsuits from vendors seeking payment.
