Who are the top five Pro shooters in PRS over the last five years?

PRS has year-end standings available on the website going back to 2015 (though for some reason 2018 is missing).

You can look at each year here:

 
The top 5 has ebbed and flowed over the past 5 years. 5 years ago Matt Brosseau was dominant but he doesn't shoot much anymore.

If you had to pick the current top shooters looking at their average scores and placements over the last 3 years, I would say the list would be (in no particular order) - Austin Buschman, Morgun King, Austin Orgain, Clay Blackketter, Ben Gossett, and Nick Gadarzi.

There are many others you could add to that list if you wanted to look at overall results over a 5 or 10 year period, such as most wins, most podiums etc. The above shooters are just who is at the top of the game right now.
