I agree with the fielding teams and not enough kids, however as far as shutting down small schools or consolidating schools should be very rare and not because they can't field a team. Just my opinion.
In the late 50s there was a game that was played in the Sam Houston Coliseum that was 2-0 and if memory serves me right it was Lamar and San Jacinto Hi schools. Just can't remember who won but I believe it was Lamar with 2 FTs at end. I am sure I will get corrected if wrong.
