Lincoln County dominated the first half on the line of scrimmage, so kudos to your son, Tn2164, if he were part of the unit that was blowing holes open.
Don't know exactly what the adjustment was, but JPII's defense rose up and stopped the run in the second half. Three Lincoln County turnovers in the second half didn't help their cause, either. Not sure why LC coach tried to pass the ball as much as he did, either--from what I saw, he didn't need to do so.
JPII won the game 24-14, scoring 17 unanswered in the second half. They play solid ball, are well conditioned, and don't beat themselves.
