I have been watching HSFB for awhile now and while most fans will definitely say a game can be lost on a penalty.
The coach him or herself will tell you, a game is not won or lost on just one penalty. They’ll likely say we should’ve never been in that situation in the first place to allow it to be perceived that the penalty caused the loss.
It doesn’t make any sense to punish the band for something they’re not even in control of.
