My dad used to coach high school and college football way back in the 60's through the 80's. At one stop, there was a rival catholic high school that almost never kicked. No punts, always going for two on extra points and no field goals unless it was the end of the half or the end of the game. Their players and coaches were cocky about it, and beat my dad's teams more often than not, so my dad never liked them.

Thinking about it further, though, their style of play broke the other teams' game plans. In general, if a defense can hold the other team to 3 yards or less they win. (Because 3 yards times 3 downs equals 9 yards and a new set of downs is 10 yards.) By calling a play on 4th down, they lowered their standard of success to 2.5 yards per play. In startup terms, they extended their runway by 33%.
