Of course. But the top 4 seeds are protected and will play reasonably close to home. So if they flip MSU frmo a 2 to 1 they have to flip their whole pod because they wouldn't send them out west to play in whatever 1-16-8-9 group that Oregon was going to play in.
Exactly, but you're talking about 2 brackets.
First off, there's the question on whether winning or losing will significantly change a team's situation. Keep in mind it's still only 1 game out of an entire season. I think the more realistic thing to say is that 1 game, even it's a conference tournament championship game, does not impact a team's seed as much as you'd think.
There's 2 games that could impact top 4 seeds today. For Texas A&M, the question is whether they have a 4 seed in the committee's eyes or not (likely yes). If yes, the game is probably rather meaningless and the outcome will not change anything.
For Purdue, the question is whether the committee has them as a 3 or a 4 seed right now. If they are already a 3, then they will not go higher and they will not go lower with the outcome of today's game. If they are currently borderline 3/4, then they could go from a 4 to a 3 with a win.
For Michigan State, a win and they are likely a #1 seed. A loss - and maybe they still are a #1 seed, or they flip with Villanova and Villanova is the #1, MSU the #2. Either way, I don't think it would change that much - Villanova would be the fourth #1 seed, which means they get slotted into the St. Louis location (which is where MSU is currently in Lunardi's bracket). Then MSU is probably put in the St. Louis #2 seed, with Xavier being pushed to the Brooklyn #2 seed.
Overall, it's not like these games will cause the committee to spend hours re-seeding/placing teams. And it may all be a moot point - the committee may view MSU right now as a #2 seed still no matter what. Or it may conclude that if MSU loses to a top 15 Purdue team, they shouldn't drop from a #1 to a #2. So the outcomes of today's games may still have 0 impact on the seeding/bracket.
