If you drill down on this one-adhering to that sacrosanct rule, obliterates any adherence to the #1 vs. #16, #2 vs. #15 in round one. Also destroys seeding integrity for the regional finals, where #1 should face #8, #2 vs. #7, #3 vs #6, #4 vs. #5. This might be the year where the committee realizes they are upending all other seeding rules, to remain stuck on the ancient (but admirable) thought that intra conference matchups should be avoided. Lastly, there are 5 NCHC teams in your tournament above, which allows them to wean off this criteria.
If Cornell were to pull a huge upset and win ECAC, they could face North Dakota, and Bemidji could face BC.
