In order for something to change in that regard, one of the teams will have to be the first to relinquish the setup duties. I doubt either team will want to be the first lower their advantage by giving up that control, so I think it will continue to persist like this.
I don't see Europe wanting to give up control of the setup in Rome especially after how well France went when they controlled the setup and how they will be seeking revenge from this most recent loss.
I also don't see the US wanting to give up control of Bethpage, because at that point they'd either be going for 3 straight, or coming off of a loss in Rome.
Also, home fans play a pretty significant role in other team sports, think like loud noise in football stadiums or basketball arenas, so I don't mind the home fans adding an advantage for the home team as long as they don't cross the line.
Is anyone else a little concerned that the Ryder Cup has too big of an advantage for the home team? Except for Medinah, the home team has won every Ryder Cup since 2006. Is that just a fluke or is something going on there? I'm wondering if the combination of home fans plus controlling the set up makes it so the away team doesn't have much of a chance at winning, even when they're better. Rome might be different, because Italians don't really care that much of about golf. But I think it's tough to see Europe winning in the US anytime soon. Bethpage could be really ugly in 2025, both in score and in fan behavior.
Great pic, it's crazy how flattened the greens look when watching on TV. I have seen a couple pics similar to yours of other greens there and the undulations look so much more severe than how they appeared on TV.
