Who cares whom their best OOS is. All that matters is who are the best teams they have beat. They won CIF SS big boy championships in 2014 and 2015. They have beaten most of the best teams in Cali, including MD, SJB, and DLS back when they were nationally elite. Cen10 has no need to, nor has the ability to, raise money to travel the country to play teams when there are plenty of good teams to play in Cali.
