I love hockey.  I'm a HUGE Bruins fan, but I just generally enjoy the sport a lot.  Of course I want the Bruins to win, but in a pinch, I'll settle for the Canadiens and Rangers losing.  
I enjoy NHL games, but they lack a passion that lower level leagues have.  US college hockey games are a blast, especially the BeanPot games in Boston (an annual tournament amongst local universities).  BeanPot games can make even the sterile new Fleet Center rock.
Mostly, I like games where the players still play for pride...
