Yeah, pretty sure the phrasing of "vacating" the win means it's no longer attributed to Michigan State but it doesn't flip to the opposing team either. We can claim 5-6 instead of 5-7, but not 6-6.
Vacating wins might be the dumbest concept in sports. The game happened, you can't take that back. We lost to MSU in 2023, I was there and witnessed it.
