I watched the SR and Martinsville scrimmage. When they played a quarter with clock and chains, Martinsville scored 2 TDs and SR 1. It was a good scrimmage. I paid very little attention to the part of scrimmage where they ran 10 plays, with no chains and clock.
As for Gretna and SR, I only watched very little of it. Gretna had too much speed for SR in the little bit I saw.
