There was a time when CBS basically had only one game on at time and sports fans were bound by whatever game that network chose to show in your area. Now CBS has partnered with a few other cable channels so we're able to see many more. That's a good thing.
But it means searching for the channel number of these extra networks. Here's what I've found. The network numbers are for Charter since those are the only ones I know. If you don't have the high def digital box, I can't find the channel numbers.
CBS 4 or 704
The Billikens of St Louis University will play at 6:20 CST on TNT
