I have a connected HD antenna, Apple TV and high speed wifi, but no cable or dish provider. The last 18 months, I've paid for Sling and used the app on Apple TV, but never really watched it and cancelled a couple of months ago. Now that football season is approaching, are there services that folks recommend from a value perspective? Michigan sports and HBO are really the only things I'd like access to that I don't have today. Thanks in advance for your input.
