It's called timing. The timing just isn't right at this moment. In the B1G's case, this is a lifelong commitment.
There are way too many question marks at this time that make the targets that the B1G craves too hard to get at the moment. But, with time things may/will open up.
#1 - Does the Longhorn network work? Right now it is a bust. Besides a few small outlets, who even gets the network let alone watches it. If ESPN keeps demanding high fees and keeps striking out, how quickly does ESPN try to buyout the contract or re-negotiate it? OR, maybe it becomes a huge revenue source. Right now Texas thinks it will be a boom, but if it becomes a bust, they might be more willing to play ball.
#2 - How much bigger does BTN become? Face it, the BTN is still growing and as it gets bigger, it will make the B1G that much favorable of a destination.
#3 - How does the Pac12 Network do? While they own 100% of the network versus BTN owning 49/51%, they also don't have a rabid fan base like the BTN does, so ratings/cable fees may be lower. Plus owning 100% of the network means startup costs could be staggering. Does it start turning a profit as quickly as BTN? How high is the ceiling? If it turns a profit quickly and with 100% ownership starts giving them crazy money, then they have a decided edge in the expansion game. BUT, I just have a feeling since they have 100% ownership PLUS a less rabid fan base, they may have tougher sledding. Afterall, IF Texas is a prime candidate, the Pac12 is the B1G biggest competitor for them.
#4 - NBC/Notre Dame TV Deal. So how much does NBC pay a Notre Dame that can barely win 7 games a year? Do their ratings keep going down? Or does NBC (or maybe another network) ponies up money to keep the party going?
#5 - The wildcard... The B1G TV Contract Negotiation. If the Pac12 is worth $3billion over 12 years, how much is the Big10 worth??? The B1G has the 3 most popular teams, biggest fan bases and combination of huge media markets and population. The contract is up in 4-5 years. How big can this contract get? Safe to just double the Pac12 deal? And that is just by standing pat. Heck, in 4-5 years what does TV look like? Do we even need to sell these rights to ABC/ESPN. Or some combination like only selling 2 games a week to ABC/ESPN (or Fox/CBS/NBC whoever) and then add more games to an expanded BTN?
Think of this, all these recent TV deals finally caught up to the B1G contract they signed back in 2006? We are not just talking about a ton of money... we are talking about a shitload of money... heck, we are talking about being able to buy and sell every other college out there type of money.
What if the B1G waits til 2016 to expand... AFTER the new TV deal is signed that basically pays the B1G twice as much as anyone else gets? While everyone is in the $20 million per year range, the B1G gets $40 million per year?
That gives the B1G the upperhand on everything. Right now it seems like everyone is making similar money with all the new contracts. While I am sure Delany is painting this picture now telling the teams he wants how much money the B1G will be rolling with in 5 years... that is still 5 years away. While you can sell on what will happen, you have better leverage the day after that new TV rights deal is signed and you can show them proof that they can double their TV money by going to the B1G.
