I'd love to see some sort of alternate stroke matchplay event, either same gendered or mixed (or both? :P ) in addition to the traditional stroke-play tournament.
The lack of any team event at the Olympics has been an objection from a lot of pro golfers from the start. The Olympic golf tournament really needs something to make it stand out, and frankly just making it a matchplay event wouldn't be enough IMO (there is already some big money "world championship" that has that kind of format).
Also, being a top 300 golfer is... not bad. There are a *lot* of pro golfers.
