Big Ten improved its product tremendously.
Big 12 did what they had to do. I know we like to rip on them ("Other 2," etc.) but they had a pretty exciting season with so many teams competing for a conference championship that would not have been in the running in their old situations, as Texas and Oregon would have dominated the Big 12 and Pac 12 this season. I'm sure all those fan bases are ok with the situation their in (for now).
