If you don't get espnu look it up on reddit. I found a stream on there that works fine. If you do I would strongly suggest you get an ad blocker like ublocker. That's what I have and works pretty well.
I figured it out: go to watchespn.com and click on any show that will open the video player. Then on the right side ESPNU says "Brian and the Boz" is playing... click on it anyways and the Gophers game pops up.
