Agree, but there is a long game to realignment. OR/WA wouldn't be among the Big10's top 5 media values (OSU, UM, USC, PSU, Wisky), but they would be right after the top 5. So not additive to the current Big10 TV deal- but more valuable than over half the current Big10 schools.They aren't just matching each other just to match. They make these deals when it makes financial sense, not just getting larger for the sake of getting larger. No department wants to take lower revenue for the sake of size.
There's no current big 12 school that is going to be financially additive to the current big 10\SEC. Its debatable if there's one in the PAC at this point as Oregon\Washington may not be at that level even.
The other angle could be structuring the 12 team CFP. A couple more high-end schools might be valuable depending how payouts are structured for conferences and potentially the 12 invited schools. It's crazy to comprehend- the 11 playoff games could earn college football $2B annually, more than the combined annual value of the Big10 & SEC media rights deals.
If the Big10 can add OR/WA for somewhere between the Big10 & Pac12 (if they get one) media deals, seems like a no brainer for the Big10 to add a couple solid brands now, so there is a track record prior to their next TV deal around 2030. Especially, if streaming is the wildcard in future TV rights negotiations.
