I was able to stream for the Ga Southern game. First time I had tried in a few years. Idk if you'll be able to for a bigger game or not (more people on the network/towers), but it worked well for me the whole way through College Gameday.
Will definitely use up some data though. Mine's unlimited, but they have the option to throttle service after I've used up a certain amount of data. At that point, I highly doubt I'd be able to stream anymore on a gameday.
