" In your scene then every A team should just play up. no team should be allow to play up..."

No. At every age group from '19's on down there are probably 2-3 LI teams that are head and shoulders better than their on age competition-usually from the 91 or LIE programs that beat ALL their local competition and 50% of the competition at least a grade up, so I understand them playing up rather than get paired vs. a mediocre on age team and winning 15-2 at a local tournament because for the most part, the MD teams don't come up to LI for tournaments.
