That's the only official way. I'll use the WatchESPN app on my Apple TV so it's easy to stream on my TV. You can get it on any device that has the WatchESPN app.
It's not a bad way to watch if you have enough bandwidth, but sometimes the broadcast is a little behind if you're listening to Cliz.
Wisconsin, Michigan State, Maryland, and Indiana are also in action this evening.
Bring on the season......finally!
