It's way too boring, nobody wants to watch people hit balls into holes, that's also why baseball isn't an Olympic sport. It also doesn't require much athleticism. It's either you hit the ball good or you don't while other Olympic sports have better techniques. Golf is not a good Olympic sport.
Golf is a good sport to watch before bedtime. What do I mean? Golf is boring, that's what I mean. It takes so long for the players to hit the ball, and that is all they ever do. So why is it an Olympic sport? I do not see much in golf, so I do not know why it is an Olympic sport.
