Not Jon, but I'm not sure this is a winnable fight.
What "weapons" or threats do you have that would cause the BTN (I don't think Barta has any influence) to change their thinking and be willing to lose money by televising, for example, an Iowa-Louisiana Tech Tuesday night game during Christmas week?
If your argument is: "We want to see all of Iowa's games on the BTN!", you're wasting your time. You need to have something in your arsenal that will have a negative impact on the BTN's bottom line, or else they won't listen. And if you're going to be mad about this game, then just tune in for Iowa-Illinois next week on the BTN, then you're not going to win, either.
If I'm the BTN and I get your e-mail, here's how I react ...
1) We don't have the resources to televise every single nonconference game for every Big Ten team. It's not cost-effective
2) The game was available to watch online for a small fee
3) Every Big Ten team has games that are only available for online streaming, or not televised at all
4) No one ever promised that all men's basketball games would be televised
5) The game was not even close to a sellout. It's tough to sell advertising to a mid-week game between 2 mediocre teams that can't even draw more than 10,000 people. That is indicative of the interest in Iowa basketball these days
So what do you have besides, "I wanted to watch the game" to argue all that with? Are you willing to pay more to help offset the money that the BTN would lose by showing the game? Is the BTN not giving you something that you were explicitly promised?
