Like others have said, the decision to go from D4 to D2 was a real head scratcher. Jeez, even a move to D3 would have made more sense (Salesian is the only beast there, and also a candidate to getting called up). But I don't think there's any reasonable way to look at D2, D3 and D4 and say "hey, D2 is the easiest route to Norcals or a state title."
Regardless the reason, CN's season is now over despite having been gifted a high seed (no way Moreau gets an open bid). It almost certainly wouldn't be over had they not petitioned up. Somebody needs to have the stones to make him answer for this and ensure it doesn't happen again.
