So this "single unit" aspect is actually what they used in the baseball tournament fiasco a few years ago. This was when there were 3 teams tied for the last two spots. The league publicly put out the seeds and brackets, and then went back to throw in this tiebreaker that changed the seeds. I remember a text thread I was on with an assistant AD at the time of one of the schools, and it was just a complete disaster. I'm still not 100% clear on what/how it happened.
