To me, I just don't get the Miami idea. I just don't get the sense that they "fit" in any way, shape, or form.
You don't have a pairing for them either. UT/OU would have been a bit of a difficult fit in a few ways (geography/culture), but at least they fit as large, public, research schools, flagships universities of their respective states, and with rich tradition in football. Miami would be a weird outlier shoehorned into the conference for what, access to S.Fla recruits? How many of those recruits really want to spend a winter in Madison WI anyway? If you could add them as a pair, say FSU/daU, maybe they'll feel a little less stranded, but FSU doesn't feel like a program we'd want to add either.
Miami had no real football history prior to Schnellenberger, and their program has tremendously fallen off after their 20-year run of relevance. They don't have much fan support. They don't even have a stadium of their own. It seems like on top of all the cultural/other reasons they don't fit, adding Miami would be like trying to catch a falling star long after its rise.
They don't belong in the B1G.
