Great point, but I think Griffith is doing themselves a disservice by playing in a much weaker league. It doesn't prepare them for the tournament very well, or maybe they like getting bounced 56-0 in the first game.
I think it would be as wise to play an established national high school power such as St. Thomas Aquinas (Ft. Lauderdale, FL) or Westlake (Austin, TX).
Or if the DAC does need to expand, although I don't think it does, they could stay local by adding teams such as Hammond Central, Hobart, Lowell, and Munster.
I agree with that and think the old NSC teams have made a pretty clean break. As for the DAC, the time zone issue is a thing and we all must remember football is just one of may sports to be considered.
