The reason we have 4a, is to create four divisions where teams are relatively equal. If the top 4a school played the top 1a school it would probably be a blowout. This is not to claim some top 1a- 3a schools are not as good as some top 10 4a's, as SMU has beaten several top teams from various divisions. But there is little reason to implement such a tournament. The all-star game which includes some of the top kids across the province, from all the different division is a better system.
