For them, they have been good enough that it is not really for 4 quarters. It has been for 2.5 to 3 quarters most of the regular season. Their dudes are still fresh (or as fresh as you can be after 9 games) when they roll into the playoffs. New Pal, GFC, and MV all were programs that 15 years ago people around the HHC knew could explode in numbers and success with the right people driving the ship.
As far as kids from other districts around them coming in, it has seemed less at New Pal in numbers, but what they have had move in has been high quality. Families want to go where there is success. Can't blame them!
