I’ve spent some time looking into this as well. Here are the two most viable options without dish or Comcast.
Sling: $50 gets you pac12, Fox sports and espn. Downside is you can’t record games on ESPN.
Fubo: Similar cost. Pac12 and fan, but no ESPN. That seems like a deal breaker as a few games a year are there
Neither will get you Root Sports for Jazz games. Does anybody use a VPN? I’m curious if that give you more options. I know Pac12 Networks streams international ly.
