I'm not sure about the ESPN/U part...but yes, ESPN+ has the option to switch mats - I think they also have a screen with who is wrestling on each mat. I usually have track/flo open to see who is coming up so I dont' miss anything. YOu might consider adding ESPN+ if you already have Hulu or Disney. I think by itself it's 9.99 per month. I did it for the Big 10 for one month during the prime dual season then cancelled it.
