The money wouldn't end up equal. Anyone who thinks it would needs to be drug tested. 99% of America doesn't care about the teams in the Big 12. Adding Clemson and FSU wouldn't change that. Adding Clemson, FSU, and NU won't change that.
The leftover Texas schools and the Utah schools don't generate ratings. Same for the Kansas schools. CU is hot right now, but will they be if they have another 4 win season? They will fade if they don't do something this year. Clemson is a regional team. People cared about them when they had lottery pick qbs. Not so much anymore. FSU might be slightly better, I don't know.
If any of these remaining teams have any real value they will be scooped up by the Big 10 or SEC.
I notice you conveniently left out ND? What about Miami and NC? Seems like a pretty strong little league to me. Two true bluebloods, a few fringe players, some basketball powers. Seems on par with SEC/B1G to me.
