You could use the espn+ matcast app. It never cuts out. There are no commercials. And it’s like you’re literally in the arena. I had to pause to pee. Best ncaa experience ever. For like $12 or wherever it costs.
I also have secondary and tertiary devices with individual mats I want to watch. In the form of my fleet of new and old iPads.
edit: All my kids iPads are “mine” for the tourney
