Just my opinion butIn what world does TCU or WV have more pull than Missouri? You do realize that the SEC could have taken TCU, but passed, and WV begged to get in, and they took Missouri over them.....
You are probably right about Colorado though, seems like centuries ago when they were in the NC hunt every year, and had AA players being drafted into the NFL every year.
WV> Mizzou from a national pull standpoint as they have been better for longer
TCU>Colorado from a national standpoint due to recent success. That and Colorado doesn't even capture their local market
So collectively WV/TCU is greater than Mizzou/CU.
