This was my original thought was well, until I looked up the date for Worlds this year..... they changed the weekend, so the blame lies on USASF for having worlds a week later than they have in the past. This is problematic on so many levels - it affects STUNT, and it happens to fall during finals for many colleges, so although the Senior teams won't be affected much, I imagine the International teams could have some athletes who can't participate.
Worlds is now April 29- May 1; Summit is now May 5-7. Programs literally have no down time from the time their season ends until tryouts. I'm curious as to why USASF/Varsity decided to lengthen what is already a very, very long competition season.
