The FedEx Cup playoffs were copied from NASCAR. It was supposed to add some excitement to the end of the season. Golf unlike other sports didn’t have a champion at the end of the season.
So it added something in addition to the 4 Majors.
Accumulating points for playing well during the season and having playoffs seemed like a good idea. And it was. It took a few years to get it right, but it does what it was intended to do.
The LPGA and Champions Tour each have their version and I think it does add some interest.
