There is no KSHSAA rule which disallows a school from entering teams in two (or more) different tournaments on the same weekend. That is, a school could choose to send a team or partial team to tournament "A" the same weekend as entering a team or partial team in tournament "B."
Greg,
This is one tournament. Friday morning pool and fri/sat bracket. One tournament! No one in Kansas has ever (to my knowledge) utilized this format. This is a great format. I am sure that someone at Kshsaa will figure out a way to shut this format down in Kansas!
