On the subject of eligibility. The KHSAA does not govern middle school basketball. However when a middle school player participates in a varsity sport then they become part of a team that is governed. Example, a first year 8th grader could not play varsity basketball and hold back in middle school to get 6 years of eligibility. He would only be allowed to play for 5 years.
Not playing in the same grade for two years because of staying back for age and maturity is a local rule. Many systems let them continue to play.
