Normally, despite the fact that I never played hockey and played basketball, I think the NHL playoffs are generally more exciting. Still, the Bulls-Celts series is fantastic. Of the six games so far, four have gone into overtime, the most in NBA history. There have been seven overtime periods in those four games, the most ever. The Celts are the defending champs, but they're missing Kevin Garnett, who graduated high school in Chicago. The Bulls missed the playoffs last year, but drafted Derrick Rose, who graduated high school in Chicago.
Even if the Bulls win the series, they aren't going far in the playoffs. But it's been a very entertaining playoff series.
