Now is the time to build Missouri St. up and give them a Big 12 invite. 
I would love the Big 12 to start subsidizing schools like Missouri St., Creighton, and some school in Colorado to help there programs surpass the losers that left.
Or give selected rivals money to ensure that Nubb, MU, and Aggie never go anywhere, like Arky, or Iowa. Note how I did not mention CU, because they will suck on their own.
