Look - without holdbacks the Crabs are NOT any better than any of the other teams in HOCO elite. Get over it. If HOCO were actually to enforce their rules Crabs would not be able to field their holdback lineup. From the HOCO rulebook:

The Conference follows a grade based system based on the player’s current grade level and assuming normal progression of school to graduation.

There is nothing NORMAL about the progression of the kids on their team. Gig is up in 2017.
