There was some conversation recently about Purdue potentially pushing us out of the Chicago Region by virtue of them beating us out for a #1 seed, with the presumed logic being that the Committee wouldn't "punish" Purdue by putting Illinois in a Chicago Regional with them. However, I wanted to look if there was precedent for that. A few reminders for those unfamiliar:
---
Skip ahead if you already know all of this or don't care, lol... ---
1. While #1 seeds are obviously the best of the best, the Committee officially takes geographic advantage into account for the top 4 seeds in each reason, hence why these are historically called "protected seeds." So, while there might be a pecking order, the Committee is at least theoretically trying to put a #4 seed on a favorable path, just as they are with a #1 seed.
2. The NCAA Tournament locations are obviously determined in advance for the First Weekend (First and Second Rounds), Second Weekend (Sweet Sixteen and Elite Eight) and the Final Four. While the Second Weekend locations (i.e., the "Regions") obviously correspond to the bracket, the First Weekend locations can be anywhere. As an example, Purdue and Illinois could both play their First Weekend games in St. Louis this year even if one is in the Chicago Region and another is in a different part of the bracket.
3. As is obvious, since the locations are pre-determined, the "home court advantage" a protected seed gets could vary wildly. While overall top seed Illinois' path was Indianapolis and then Chicago in 2005, overall top seed Virginia's path was Charlotte and (what would have been) Atlanta in 2019 ... all just luck of the draw for where the sites were that year.
4. Per my research, the Committee officially added the NET Rankings for the 2019 season. I'm not sure how much that changed the selection process as it relates to location (after all, they still clearly ranked teams within a seed line before that), but I'm including it just as an FYI.

My point as it relates to Illinois and the Chicago Region... ---
Back to the point, I wanted to look if there were any similar situations where a #1 seed got put in a Region where a lower-ranked protected seed had a better home court advantage ... as would be the case in the example scenario that the Committee put a #1 seed Purdue and #3 seed Illinois in Chicago this year. Since the Committee just has to sort of find a spot for NON-protected seeds (again, those #5 and below), I am limiting the examples to top 4 seeds only. After all, if Purdue is a #1 seed in the Chicago Region and we are (SUPER disappointingly!!) like a #7 seed and wind up in the same region, that isn't the Committee "rewarding" us alongside Purdue ... it's just an unlucky draw for Purdue.
Anyway, on to the list. Format is the year of the Tournament on top, the Region below that and then a list of the top 4 protected seeds in that region. Teams in
green are clear examples of the lower protected seeds having an even better home court advantage there than the supposedly "more protected" higher seeds, thus giving us hope for sharing Chicago with #1 seed Purdue even as a #2 or #3 seed. For fun and to add some subjective element, I made the especially egregious examples in
bold font, too.

--- TL;DR ---
So in the 25 NCAA Tournaments since 2000 (with 2020 being cancelled), there are 20 examples of a 2/3/4 seed being put in a Region with a #1 seed, where the "worse" seed has a very clearly better home court advantage ... ala a scenario where a #2 seed Illini team is in Chicago with a #1 seed Purdue team this year. I will say that for the especially clear examples (e.g., #3 Syracuse being put in Albany, NY with #1 Oklahoma in 2003), there seems to at LEAST be a sort of pattern of wanting that team on the bottom half of the bracket (i.e., a #2 or #3 seed rather than a #4) so as to not make the #1 seed face them in front of a hostile crowd until the Elite Eight ... so let's shoot for that #2 seed or better!
Of course, the Committee could decide it would be unfair to add #2 Illinois to Chicago with #1 Purdue ... but there is a TON of precedent that they could also prioritize "protecting" a #2 seed Illini and adopting the attitude that if they don't face each other until the Elite Eight, it's fine.
P.S. Funny side note, but I left off the example of #1 Kansas in Las Vegas with #2 UCLA in 2023 because of how thoroughly we dominated the crowd in Vegas that very same year vs. a much closer UCLA.
