In the 1930–31 season, he played all 44 games again, and was named to the Second All-Star team. In the next season, Boston lost the semi-finals of the playoffs to Montreal. In the second game of the series against Montreal, Thompson was removed from the net near the end of the game. That was so done so Boston would have six attacking players against Montreal's five. Having more attacking players gave Boston a bigger chance to score. Although Boston lost, their coach's idea was described as "amazing".
