I have (an older) Roku thingy... can anyone give me a detailed, USMC-proof explanation of how to get the Bammer/Vandy 2:30 Game on CBS?

I've got the "CBS Sports" channel added but am at an impasse... don't see it listed...

WARNING: I am supremely ignorant (at times) with this shit... it'll prolly take some "hand holding"...

Thanks.
