No reason a fourth MA college can't be invited to play.
That would be interesting.
Umass Lowell or Merrimack would work too
I really wish they would expand the Beanpot. It would add some intrigue.
I understand why you all feel that way. If other schools in New England want some sort of annual tournament they should go make one. The CT schools (UConn, SHU, Yale, QU) did so last season and I think it was fairly successful.
I can't speak for all of us, but as an alum of one of the Beanpot schools, there will never be an interest in having a team from outside the current four. It is not an invitational tournament.
