You could get rid of E/W and do a podded system of...
ISU / UC / UCF / WVU
four Texas schools
BYU / KU / KSU / OSU
Play the rest of your pod every year = 3 games
Play three of the teams in the opposite pods each year = 6 games
Basically a full round-robin but you miss two teams (not in your pod) per year
This would guarantee everybody has (at least) one Texas road game per year
Put the two best teams in the CCG -- no divisions.
Basketball...? Well, why not a double round-robin of 22 games?
I don't really see why this is more attractive than divisions with 2 & 2 Texas schools, which can also guarantee one game in Texas every year at a minimum. With 9 conference games in a 12 team league you are playing everyone very fast. Even with a protected crossover, you won't go more than one year without playing any given school; i.e. if you are not playing a school in a certain year, you played them last year and you will be playing them again next year.
I really like the idea of going big with 22 conference hoops games. Why not? Throw in Iowa and a preseason tournament, a couple tune ups at the start, and a couple other interesting power-conference games, and you are at 30. I don't want to see us play Prairie View A&M seven times in November and December anymore.
