Sports is rife with subjects that fans can bat around in spirited debates. With a storied history dating back to 1917, the National Hockey League has plenty to offer in that regard, as demonstrated in NHL Top 10. The series runs the gamut of hockey "bests" and counts them down from 10 to one, with each half-hour episode focusing on a single topic like goal scorers, team rivalries, game-winning moments, toughest places to play, and U.S.-born players. Included with the highlights are commentary and analysis from current and former players, as well as broadcasters and journalists.
