Those are your words not mine.
However now that you mentioned it. The fact that OU played only 9 games against top 25 competition, fewest in the WCWS, while Florida played 33, Georgia 23, Oregon 21, ASU 18, Washington 18, UCLA 16 and FSU 12 might have some thinking the other teams did play a tougher schedule and may be more well honed for playing against top competition. Check the Nitty Gritty. Also note OU played the fewest number 13 of road games (tied with ASU and Georgia) of any team in the WCWS. FSU played 21 and Florida 19.
I acknowledge their is little OU can do to overcome that scheduling advantage for the SEC and Pac 12 thanks to the departure of Nebraska, Missouri and aTm from the Big 12. But is wrong to not recognize the schools in those conferences play a much more difficult schedule. With a tougher schedule OU is probably seeded #1 or #2 instead of #4. But if you don't play the SOS you don't get the seed as SOS counts for 75% of the rankings with a little "eye test" thrown in at the end to tweak the seedings. This year their eye test only bumped Tennessee and elevated Georgia in the top 8.
It works just like the Pac-12 and the Big 12 football teams being penalized while contending for the CFP because of their weaker football schedules. Also driven by conference affiliation and weaker teams.
Patty attempts to mitigate the situation with her non-conference scheduling as best she can but she cannot overcome the numbers game. OU attempts to do the same thing in football but scramble to make the #3 or #4 spot as they are never seriously considered for the #1 and #2 slot.
It is what it is unfortunately. And while I would like to see winning percentage count a little more in the RPI and SOS at little less to give teams more control of their own destiny I do not have the evidence to prove it would make the RPI system better and it is very successful now. Nor are other unsubstantiated desires for change a concern of the selection committee.
