I understand the opposition but reality is it is what it is.... times are changing.
Now would you feel that way if the Pac 12 goes to 16, SEC to 16, ACC to 16 and the Big 12 to 16 and the B1G stays at 12. What do you think will happen long-term to our future TV contracts, bowl invites and overall competitiveness? Again, stay put and we will be left behind. Under that scenario what if an Ohio St or Michigan is poached in the process however hypothetical? Do you think the big dogs of our conference are going to be happy being in a less prestigious conference compared to the other super conferences? You see everyone basis things off the past but the future could be drastically different if the B1G is not on the forefront (like it always is... think of the addition of Penn St at the time which made an odd number of 11 -> why do that?)
I absolutely feel the Big Ten can remain competitive as a 12 team league regardless of what everyone else does. There is a finite limit to tv contracts and the more teams you add the more that $ gets divided up. Again the Big Ten has the largest fan base in the country, so there will always be tons of subscribers willing to pay for the BTN. If the SEC goes to 14 I don't think the Big Ten will react. If the Pac 12 and ACC also increase, then the Big Ten might act. I'm not saying it won't happen, I just hope it doesn't. You are calling it a foregone conclusion. As we have seen in the past year, these situations are amazingly fluid, so to try to predict anything right now is just pure speculation.
If the Big Ten signed a $300 million dollar tv deal (which is a very real possibility in the near future), each team would get $25 million. A 16 team SEC would have to get a $400 million dollar deal just to equal what the Big Ten gets per team. That's a 33% premium for just 4 more teams. Maybe ESPN would give it to them, but I doubt much more. So the reality is they aren't any further ahead and they have completely sacrificed the tradition of the league.
