Costs money to broadcast games and basketball season has too many games. In football ESPN/ABC get first dibs on every game so Im guessing itste same with ESPN. If they're willing to spend the money to show a game online then they'll do it
Honestly, you have your own network. This needs to be ironed out. The idea is to be seen by as many viewers as possible, not as few.
I'm not sure of the particulars, but it appears that the Big 10 let ESPN have a few ESPN3.com 'exclusive' games as part of their contract. They have chosen the NDSU and SDSU games as they are more attractive then say Eastern Kentucky. Also, I don't know what the BTN aired tonight, but it's possible they wouldn't have carried it anyway. In reality, the BTN should want to air the NDSU and SDSU games as they want distribution in the Dakotas where they don't already and ratings where they do.
