College coaches are currently in season until they hope they end of May. They have their own teams to worry about. They don’t have time to go watch high school games while in their own season. 5/31 will stick. Highly doubt they will extend it past that when summer tournaments kick off in June and it will have been a year since players were watched from a sideline.
Who knows but I highly doubt the NCAA is thinking about lacrosse tournaments when making these decisions.
