Of course recruiting is very hard if not impossible to prove. Unless the athlete is willing to give up the coach that recruited him (highly unlikely), I can see no way for it to be proven. Past cases of recruiting, as I recall, centered around private schools and the elimination of tuitions. From reading the KSHSAA regulations concerning hardship cases it appears there are means to bypass the administration from the former school (appeal to the board), in order to determine if the hardship is legit.
