I don't know about that. If it ends up being $10M/yr. plus their increased travel costs for all teams (which will be in the same ballpark), $20M/yr. is a big chunk out of the projected annual payout of $100M. Then they have to compete at Big Ten scale on 4/5 of the other programs' budget. That's not trivial.
I was very worried about this stuff in the summer when there was some possibility of a Pac raid on the Big 12 that might leave TCU out in the cold, especially when we hadn't been worth a darn at football in five years. Our football program stock is currently (as y'all may be aware) pretty high, so that problem is fixed for the near term at least. Plus with the recent Big 12 TV deal I don't think there's any need for our conference to 'go big' or suffer irrelevance. I'd still take the 'four corners' schools if that were available, but I don't want Oregon or Washington for the simple reason that they don't really want that themselves. After all these years I'm very excited to see TCU in a solid, more or less major conference full of competitive programs all basically on the same level and with no malcontents who think they're a bigger deal than everyone else. I can't wait; it's going to be awesome.
I think the best thing for everyone, and the most likely at this point, is for the Pac N to sign a TV deal that is roughly equal in numbers to the Big 12's (probably with some role for Amazon), and for us all to let the impact of the new playoff format on the college sports landscape play out. I'm guessing that the likes of Oregon, Utah, TCU, K-State, etc. are going to do pretty well out of having a clearer path to the playoff than some UCLA, Aggy and Texas types. That should stabilize things.
