Back in 87 or 89 prior to the World Championships, ESPN aired the US Team Trials tournament from a site called Wet Set Village in California. I remember being inspired by seeing many age-group competitors in addition to the Open Division skiers. It was a cool tournament to watch.
Fast forward to today, why wouldn't USA Waterski select Blaze Grubbs to be on the Pan-Am team? Or, if he was unavailable due to Collegiate Nationals, send a 3-eventer who wasn't involved in Collegiate Nationals.
It makes it clear that there isn't many high level 3-event skiers in the US. Not like a few decades ago...
