Hockey is a big deal in the Boston area. Just look at the Boston Bruins’ rabid following as evidence. Every February, however, the Bs share their arena, the TD Garden, with another local, rink-related obsession: college hockey, specifically the 64th annual Beanpot hockey tournament between the storied men’s programs at Boston University, Harvard University, Boston College and Northeastern University. The first round, in which BC faces off against Harvard and BU takes on Northeastern, takes place on February 1. The winners then square off against each other on February 8. The BC Eagles have dominated in recent years, yet hope and enthusiasm remain among the other teams’ supporters that they can earn year-long bragging rights to the city.
