This is from Golf Digest, and it makes sense that the Saudis did this to gain leverage in negotiations because the PGAT has been talking to other investors:
For the past two weeks sources have told Golf Digest that PIF looks at Rahm as a bargaining chip amid worries the PGA Tour will ultimately walk away from the proposed framework agreement, the belief being that the tour could not afford to lose someone as valuable as Rahm. With Rahm in tow, it certainly bestows leverage in PIF’s corner and could force the tour to accelerate its deal with PIF to minimize collateral damage. That option is on the table. Conversely, there are a number of voices with the tour that deem Rahm’s separation as an act of war and that it violated an unspoken agreement between the two parties (since the no-poaching clause was eliminated from the deal due to antitrust regulations). So, in spite of the outside belief this could force the sides together, it could do the opposite. The ball is truly in the tour's court to prevent this schism from spiraling further out of control, but it is unclear if decision-makers with the tour have any hunger for cooperation after Rahm's exit.
The thing is that if the addition of Rahm is the tipping point to force a deal between the PGAT and PIF (which I would guess is the primary motivation for Rahm signing; he's going to get his money, and was told that a deal is imminent with PGAT, which among other things will allow him to play in the Ryder Cup and several elevated events with PGAT players), it's going to be structured to benefit golf's stars, and will screw everyone else (the Saudis money gave the leverage to the golf's stars).
There will be around 10 combo events for the stars of LIV and the PGAT, but while they will likely be 72 hole events (so was the Hero World Challenge; so, its not really a big lift to play golf four days in a row), they will have no cut and will have restricted fields. Boring massive money grabs. The PGA will continue with some of its other events with the promise of a few players qualifying for these super combined events, but those fields will be watered-down and feel like the glorified Korn Ferry tourneys; LIV will keep some of its own irrelevant events, particularly those in the Middle East and maybe a couple on Trump courses, but those events will continue to be a tree falling in the forest with no one there to hear it.
Agree that golf will be irrelevant, or at least not as fun to follow, except for the majors. Then, again, even though the fields were weak, actually thought a bunch of the Fall PGA events were really fun to watch (and bet on).
