Can a high school senior play on JV football team per chssa rules?

No, a high school senior is not allowed to play on the JV football team per CHSSA rules. According to the CHSSA Handbook, "Seniors who have not been declared 'ineligible' due to grade average limitations may not participate on the JV team" (Section A, Article 2, Section 10). This rule is in place to ensure that senior athletes are competing at the highest level of competition and that there is a balance of competition between teams.
