My son Plays SuperStar box and our teams are grade based. So a 7/8 grade team or 8th even with hold backs can play in the lower(A) bracket if it chooses. AA is always straight 8th grade including hold backs. A or lower division is usually straight 7 or 7/8 teams. 91 has been playing down for last couple of years so it makes it hard for a straight 7 team to play a 8+ hold backs team who are often 2 years older and obviously much larger.
