Here's why (from a Sooner point of view) a league with mighty Texas/ powerful Oklahoma & stellar USC brands can work:
2019 final CFP ranking before bowl games -
1 LSU 13-0 2 - SEC
2 Ohio State 13-0 1 - B1G
3 Clemson 13-0 3 - ACC
4 Oklahoma 12-1 6 - PXC
5 Georgia 11-2 4 - SEC
6 Oregon 11-2 13 - PXC
7 Baylor 11-2 7
8 Wisconsin 10-3 8 - B1G
9 Florida 10-2 9 - SEC
10 Penn State 10-2 10 - B1G
11 Utah 11-2 5 - PXC
12 Auburn 9-3 11 - SEC
13 Alabama 10-2 12 - SEC
14 Michigan 9-3 14 - B1G
15 Notre Dame 10-2 15 - ACC

ESPN 3rd tier backed schools:
ACC - 3
SEC- 5
PXC - 5
Total: 13
Those 13 brands on multiple Disney platforms that FOX doesn't offer, think indoctrinating the youth on branding, from an infatuation with "Baby Yoda"... https://youtu.be/5WF5mTKqQqA
Disney branding, puts Oklahoma smack in middle of sports programming arm with coverage from New York to Florida to Texas to California, that's power...
FOX doesn't have platforms as ESPN+/ Hulu/ Disney+ for streaming, nor 12 separate network channels available for constantly keep Oklahoma in limelight...
The list above, (as bad as XII & PAC separate of one another), has exact same total of top 25 teams (5) as B1G/ SEC tallied in CFP ranking of 2019...
This could have worked well, if Ohio State didn't "gum-up" a message of "inevitability" as ACC won with arguably worse league viewer/ revenue than XII... https://youtu.be/UOJ-bsgXT_8
I recall ESPN pushed USC all day/ every day, & we all as Sooner fans wondered, "can USC topple Oklahoma's 47 game win streak..?", Clemson threatens...
So, as said, Oklahoma has 3 options, 1 with academics but population decline/ 1 with population growth but bad academics/ 1 that offers #Smarts&Sports...
One option affords Oklahoma to keep most regional foes/ add elite AAU brands/ increase revenues/ hold on to fiefdom/ while expanding footprint of league...
Just my view of how Oklahoma & Texas keep closer historical ties while improving league, pretty much the same as the original merger of Big8 & SWC brands...
