Also, GW has not given up 30+ points (in a game that did not have JV playing in the 4Q) since the 2010 season. And even then, the 31 by LT had a garbage TD after the game was decided and 40 by the ROT lead WWS squad in the 7A quarters.
2009 - WWS had 31 in a double OT loss in the state final
2008 - ESL had 27 in the 7A semis.

If you think there will be more than 78.5 points, then it will probably be because GW scored off of a bunch of HC turnovers. GW does not get in shootouts. They will slow the game down, methodically run the ball, milk the clock, and keep the HC offense off the field.
