That's a good question. I think there is some truth to the fact that it hasn't been a big deal because it doesn't represent who skiers feel best skier in the sport.
I think there is little doubt that Gus is the best overall skier, but until this year he didn't have an X Games medal. Thus, the award kind of felt illegitimate. This year, however, I think he clearly deserves it. But consider 2012 when Wallisch won the Dew cup with 2 golds and a silver, X Games gold, Gran Prix gold and gold in other events. He was clearly the best skier in the world. I don't think anyone will ever have a season that dominant for a long time. Yet he wasn't the champion because he mainly participated in one discipline. I understand that overall means overall, but perception did not match up with reality.
In other sports, like surfing, there aren't multiple disciplines. As a result, the points more clearly align with the undeniable top athlete. As we've seen, in skiing, an athlete can sweep every major event in one discipline, and not win the overall. In every skier's mind, that's the best athlete, but the system doesn't reward that. There's clearly something broken.
Here's three things I think might make the AFP more relevant.
1. Find some way to incentivise all top athletes to compete in all major disciplines. Frankly, this will never happen since most top events are very limited (X Games invites only 12 male athletes to any one event, crowding out too many athletes). Who wants to train hard to come in 14th in one event and 2nd in another? Why not just train in one?
2. Create a new format that encompasses all disciplines into one competion, like Street League. Since few resorts will be able to build the course, you'd have to create a short series that only includes a few events with a limited number of athletes. The remaining traditional events would be a part of a promotion/relegation system. I think this might be to exclusive to work in skiing.
3. Instead of mandating a certain number of results of a certain discipline, count the top 5 or 6 results, regardless of whether it's pipe or slope, etc. Athletes, like Gus that compete in more top level events will still have more opportunities to get platinum results. This system will respect any athlete that had a historic season in any one discipline and thus be more relevant and legitimate.
What do you think would make the championship a bigger deal?
