There is a very small percentage of coaches that are exceptions, but the vast, vast majority of coaches don’t give one crap about sportsmanship, integrity, and playing by the rules, and this proves it. They KNEW it was not legal, not right, and outside all concepts of sportsmanship to try this. But they consciously and deliberately played outside the rules, all in the name of getting a “W.” Disgusting.
No, that doesn’t excuse the game officials for not knowing the rules, and allowing this to happen. But, shame on the coaches for putting the officials in this position.
