Media for teams outside of the southeast have long argued that the RPI isn't a good rating system for baseball because it favors teams in the southeast. They argue that because the southeastern teams are closer geographically that it's possible for them to play better competition on Tuesdays versus say, Texas Tceh which has nobody close enough to play a non-conference Tuesday game against a good team. Conversely Florida and Florida State played their 3-game series on Tuesday nights. It's an interesting argument for a team like Oregon or Oregon State but for the most part I see it as a cop out. The RPI is intended to measure a teams worth by analyzing who they've beaten, that's it. It's impossible to argue the fact that the Big 12's top 3 teams have a combined 17 losses against bad teams because no matter how you spin it teams outside of the RPI top 100 are bad.
His beloved Big 12 doesn't deserve two regionals, it deserves one regional that will be over-inflated to become a national seed. Then TCU and OSU will travel as 2 seeds. That's what happens when a 9 team conference has six teams outside of the top 100.
