OK my thoughts on the Washington and Oregon additions. I truly believe the Big 10 wanted to add both at the same time they added USC/ UCLA and negotiate a TV deal with all 4. But the Big 10 didn't want to have the collapse of the Pac 12 on their hands. By taking the LA market, the Big 10 knew that the rest of the league would be on borrowed time. There would be schools that would leave the PAC and go to the Big 12 or the Big 12 and the PAC would merge whatever the case. When Colorado left, then Arizona, the Big Ten believed that the PAC was vulnerable enough to take Washington and Oregon and not have blood on their hands. Everyone is giving the Big 12 credit for destroying the Pac 12, but when you look at the end results, the Big 10 has 4 of the top 5 or 6 Pac 12 brands joining their league. I am not sure the Big Ten was going to get much more from Fox/NBC/CBS with 4 additional schools than they got with the 2 LA schools.
I am not saying the Big 10 leadership was forward thinking, but they did sign a shorter deal with more $$$ per year than the SEC got, and they get to renegotiate a couple of years before the SEC.
