Both teams bottomed out with a win expectancy of around 4%. The odds of two teams with a 4% chance of winning both winning is 0.16%. Not 16%, but 0.16%, or to put it in words, it would happen once about every 625 opportunities.

You can bet that October 13th, 2013 will go down as one of the most memorable days in Boston sports history.
