I think it was bigger that. Chaminade fans were pretty arrogant. They thought the Lions winning was a forgone conclusion. After the game a lot of the Chaminade fans sat almost frozen like they were in shock.
I thought the coaching staff didn’t have one of their best days. The officials made 2 big mistakes in the 4th quarter that hurt Chaminade. An obvious fumble recovery was ruled not a fumble. The other after an incompletion the clock continued to run. It ran off 30 seconds that the Lions could have used at the end of the 4th quarter. It didn’t appear that the Chaminade coaches recognized it. The fans sure did.
