Can't wait! For those that want to watch but don't have cable - http://www.cutcabletoday.com/watch-hard-knocks-online/
Just ordered HBO for SlingTV. Best part is I won't have to call and sit on hold with the cable company to discontinue next month, all I have to do is login and uncheck the box to take it away.
I have Uverse and I just went online to add HBO. It's free for 3 months, no commitment. I have a reminder set on my phone to log on to my account and cancel it before the 3 months are up. No need to call and wait on hold with customer service. I did the same thing last year when Uverse had this promo.
HBO Now or Sling. Also if you do happen to have, or are getting cable... http://xfinity-texans.com/index.php Free HBO for 12 months to watch Hard Knocks.
Had Uverse for a long time, they must have recently set it up to cancel packages online. I always had to call to remove, but of course adding was easy. I'm happy with SlingTV for the most part especially at the price, with the biggest downside being not having ROOT.
