When I was in high school in the early 80's, my team and the opponent were both state ranked and we had a huge game at our home court. Our team was more of a methodical, take high percentage shots type, and our opponent was run and gun. There was no shot clock back then. Our coaches game plan was to do a four-corner stall and shorten the game. Basically, all we did was pass the ball from corner to corner. The score was 4-2 at halftime. My team ended up winning the game 26-24. It worked, but made for a boring game. Having a shot clock is a good thing for the game.
