Trial all of the streaming services that feature ESPN and local programming (CBS, ABC, NBC, FOX) to cover all of your bases. All these services feature a trial period up to 7 days, if I'm not mistaken.
Seeking advice from others can help, using the Google machine to research helps as well. Best knowledge will come from hands-on test driving each service and see which one fits best.
For myself, Hulu Live TV , PSVUE, and YouTube TV all ensure coverage of UGA football and pretty much every other college football game. But PSVUE is glitchy and twitchy, with freeze-ups and that makes it expendable.
I flip flop between Hulu live TV and YouTube TV from month to month, depending on which service is cheaper.
