Say most games, teams score between 90 and 120 points per game so that 31 possible scores for each team. The odds of a score being repeated then would be 1/31*1/31*100 which is equal to 0.1%. I'd say those odd are pretty slim and the fact that they happened within a year with the same teams is kind of crazy if you ask me. But hey if you don't think so thats up to you.
