Big Ten teams do care a lot about league titles (at least according to the Big Ten fans that talk about such things, like Mark Titus). SEC fans probably not as much, though now that the league is suddenly really good at basketball, maybe that will change.
I think if you moved it 1 year into the future (and so MSU lost their lone title), it would swing pretty far in Florida's favor, but at least MSU had one plus all the other success. You still cut down nets for a Final Four, and MSU had 7 of them in the last 25 years.
