St. Lawrence has clinched sole possession of the #2 seed and will be off next weekend.
Yale has clinched a first-round bye. The only way they aren't the #3 seed is if they lose to Cornell, Dartmouth beats Quinnipiac, and Colgate doesn't beat Brown.
Colgate is in 4th due to their tiebreaker win with Dartmouth, but cannot catch Yale for 3rd as they lose both the head-to-head tiebreaker with the Bulldogs and the three-way tiebreaker with Yale and Dartmouth. They can clinch a first-round bye with a win over Brown. Worst case scenario has the Raiders falling to 7th.
Dartmouth is in 5th but can finish as high as 3rd. They can finish no worse than 6th.
Harvard can still claim a first-round bye but can finish no higher than 4th. Their floor is 7th.
Cornell will be at home in the first round. They will finish between 5th and 7th.
Clarkson is at home in the first round. They will finish 8th and host either RPI or Union.
RPI will finish either 9th or 10th and will be on the road for the first round. If they beat or tie St. Lawrence they will be guaranteed 9th and will travel to Clarkson. If they lose to St. Lawrence and Union beats Clarkson, they finish 10th and travel to either Cornell, Harvard or Colgate.
Union will finish either 9th or 10th, same rules apply as above. They take 9th only with a win over Clarkson and an RPI loss.
Brown will finish 11th. They can tie Union for 10th but Union would win the tiebreaker. They will travel to one of Colgate, Dartmouth, Harvard, or Cornell.
Princeton will finish in 12th. They will travel to one of Colgate, Dartmouth, Harvard, or Cornell.
There's only one tie in the standings right now.
