For everyone worried about how the 40 sec clock would affect us in blowouts, Stephenville and South Anchorage (yep from Alaska) showed us how to do it. Stephenville was up 43-0 with 3:30 left when they started taking a knee on the South Anchorage 2 yard line. They took snap with about 140 left on the clock on fourth down but never took a knee. Both teams stood around until 10 seconds left when all started shaking hands. QB took a knee as time expired. Last play reportedly took 1:40 off the clock.
