I don't remember anything about the '72 summer games. I was like 6 months old. I've only seen the footage of the game and they usually only show the last few seconds.
As for the George Brett thing...I never understood how pine tar would or could help a hitter in that situation. It was a pretty stupid rule TBH. I wasn't a fan of the Yankees or the Royals but I always remember Brett flying out of the dugout at Yankee Stadium. The 80s were the absolute best for umpire arguments. Earl Weaver, Billy Martin, Whitey Herzog and I'm sure there are others I don't remember the names of.
