last season CEC had several kids injured toward the end of the season. they tried to pull out of the Belmont charter match in district duals, however Belmont forfeited to them first. CEC then forfeited in the finals to let the kids try to heal up and even sat a few starters out of the PCL ttournament bc they weren't recovered yet. D12 decided to penalize them this year for forfeiting last year and not let them wrestle in the district duals.
As for "entering" it's my undesrstanding that bc D12 in AA is so small they are automatically entered as they have never "applied" for it.
