That's probably because you were in the NU section. I'm a neutral who was rooting for NU; sat around center ice in the lower bowl. BC's section was louder (by virtue of having more people). The Dog House was plenty loud, and probably had more chants going on a consistent basis (and definitely more original ones- "we can't hear you" every five minutes from BC was obnoxious and reminded me of high school basketball games). But to suggest that it was louder is just stupid. It wasn't. 3,000 drunk college students are always going to be louder than 1,500.
Curious to see what the turnouts will be on Monday. BU only filled 2.5 sections, but they had the early game and traffic/the green line was historically bad- hell, the band didn't get to the Garden until almost the end of the second period! Would be cool to see each team fill 6. Either way, the place is gonna be nuts!
