I think the ultimate result is that the PGA Tour buys the European Tour and creates a unified World Golf Tour
This would have very interesting ramifications for the Ryder Cup.
Team play is an abomination though. Golf is a sport of pure individual achievement. The Ryder Cup leverages history, infrequency, and being the only team event anyone actual cares about. After that these guys shouldn’t be wasting their time with team events.
I listened to the whole NLU podcast as well, and while the guy who brought up the idea of a team event in the style of most college golf tournaments didn't get a lot of traction, for me that's by far the best way to make a team event work within the context of a "Premier Golf League" like this: if you have four-man teams, take the best three scores each round for each team and add them up to determine the team winner and standings at the end of the tournament. It wouldn't change anything about how the golf itself would be played, except that every score would matter for the team competition, and so in theory every golfer on the course (even those starting their final rounds on the back nine at the bottom of the leaderboard) could play critical shots right down to the end of the event. This would work brilliantly in the context of a Formula 1-type team model, which seems to be what the founders have in mind...not this:
I actually don't think they need to pry the best players, they can use regionality and fandom to promote the "teams". I've floated this idea around in my head for years and think it would work, but you need to sell it as The Boston Drivers vs. The New York Knickers and have teams have home courses and whatnot.
I don't think this model has any prayer of working any better than Team Tennis did - that's the obvious structural comparison to what you've proposed. Geographically based teams work in the Indian Premier League cricket tournament (another competition to which the Premier Golf League might be reasonably compared in other aspects, including the idea of an artificial-but-still-awesome team draft) because that's fundamentally a team sport, and teams can only play other teams, and those teams have to be based somewhere, and the IPL has managed to scoop up absolutely every quality T20 cricket player in the world, which in turn makes people excited about supporting specific teams. But in golf, as in tennis, events are really only compelling when everyone is playing at the same place at the same time, all competing for supremacy simultaneously as individuals (or as national teams, as with the Davis Cup and the Ryder Cup). A four-on-four showdown between "Boston" and "New York" in front of a minuscule crowd will look like a bad exhibition, not a worthy rival to the PGA Tour.
I started listening to the NLU podcast thinking that the idea of a Premier Golf League was a bad joke, no better than Greg Norman's "World Tour" idea from the mid-90s...but I came out of it actually kinda excited about it. I do shudder at the thought of how bad the courses they're likely to pick would be (as the NLU guys themselves suggested), and if executed poorly the PGL could be a real setback for professional golf. But my head explodes - in a good way - at the possibilities this concept *could* encompass, and if it's executed well, this absolutely could be a game-changer.
