This topic has come up every year for the past 12+ seasons. The INFC will never increase the number of playoff teams beyond 3 per division. In fact they would prefer fewer playoff teams with more in the PST. Why? Because the PST is double elimination and more games means more gate fees. 7th grade playoffs will be 9 teams with a 1st round play-in game between two 3rd place teams.
Another thing that comes up every year is TYAA scheming to put together a 7th grade team. I see that still hasn't worked either.
