There are 7 teams who are all but locks at this point which in the worst case scenario leave only 1 more at large spot. That would increase to 2 or 3 if Cornell wins the Ivy tourney and one of Maryland, PSU or Hopkins wins the Big Ten tourney.
Besides winning one of the next two and putting together a little run in the Big Ten tourney it's essential that Cornell wins the Ivy tourney and someone like Syracuse doesn't rip off three more wins to get in the mix for an at large. Also have to worry about Denver and UNC.
