So Boston College wins the NCAA Hockey championship! Salute! (not even sure if their hockey team is in the ACC)
BC plays in Hockey East. Had they remained with hockey in the ACC, they probably would have gone undefeated (as the only ACC varsity hockey team) That said, a number of ACC schools have club teams, and I'm pretty certain UNC would have raised a "Runner Up" banner at the Dean Dome after being pummeled by a real BC team.
