The weird thing is, if this tournament survives for ten years or so, there's a fairly good chance that a defending champ will be rotated out of the schedule. Hypothetically, imagine that champ won it four consecutive times. On the trophy, it'd look like 3-1, or 2-2, or 1-3 with some other team breaking up their streak. Not that it really amounts to anything, but it'll look weird.
Also, long term bragging rights for the Gophers like "we won it four consecutive years" will come with an asterisk from the POV of the other four teams. They should be expected to win it at least 1 out of 4 years to claim mediocre success, where the other teams need only to win it once every five years (approximately). Cue the math wizzes to tell me what that number should actually be.
