Game's at 7:30 central, and it's not on TV. You can watch a webstream of it here.
Northwestern should win this game: the line opened at -9.5 and has since been bet up to -11.5. But, they've lost to far worse teams than TCU in recent years.
Talk about the game here, just remember to be civil to your fellow commenters. And don't talk about illegal streams, although I don't know why you would since the game can be streamed legally.
