I've done this for every game that has been streamed online.
Unfortunately, my smart TV doesn't have the ESPN app (it's an LG) but it does have the screen share option. It's crazy how good of a picture it creates, and it's super easy to do, at least when using a Samsung phone.
You can find just about every FBS game each week for free at reddit.com/r/cfbstreams
If you have a smart TV, just bring it up on your browser. It may take trying a couple of the links out for each game, but almost every game is on there.
I have ESPN 3, ESPN+, Fubo with the sports package, etc., but many G5 games are still not covered by those outlets. Reddit always has them.
