I agree Matchplay golf would be a fine addition to the Olympics, singles, pairs and mixed pairs would make for an interesting program.Just out of interest, I presume you're against tennis being in it too?
I'm actually fine with both sports being in but not in their current formats. Golf should be matchplay or a two person team event and Tennis should only be doubles events. I think that way the Olympics would at least be the peak of those formats of either game. (I think anyway, there's never much buzz for doubles the rare occasions when I watch tennis)
I only mention Golf because it was one of two sports (the other being 7s) that were added over Squash in 2016.
