While the players aren't earning a paycheck from the PGA of America, I've gotta think there are some tangible endorsement bonuses from their sponsors that they get for making the Ryder Cup team. That's a lot of exposure for an sponsor. Even a clothing sponsor who's logo isn't flashed all over the screen is getting some intangible benefit from the increase in visibility and recognition for its athletes.
And when it comes time to renew that hat logo contract, walking into negotiations as a Ryder Cupper has to count for something. I'm guessing Scottie Scheffler will be pulling down a little more endorsement coin than most other non-winners on the Tour.
Also, the Ryder Cup creates interest in the PGA Tour, which, from what I'm told, creates a lot of income for these guys. From my quick calc, 23 of the 24 players out there last weekend earned pretty darn close to $110,000,000 combined in 2021 official money (Wiesberger did not earn any official PGA Tour money). Maybe it's not a huge sacrifice? But I understand the apprehension behind working for free so that a bunch of other interest can cash in. Not so much the PGA of America, but the networks and such.
