"The NHL began playing seasons of 80 games or more in 1974-75. Since that time, only two teams have scored as few as 33 power play goals in a season. With two games remaining, the Stars could tie the 1997-98 Tampa Bay Lightning for fewest power play goals in a season."^^<http://www.w3.org/2001/XMLSchema#string>
