UFC Fight Pass is a bit like WWE Network, except you don't get current pay per views until six months down the line. There's some cool content on fight pass, including the excellent 'Fighting For A Generation: 20 Years Of The UFC' documentary. CM Punk will prove to be another engaging subject for a UFC documentary. If anyone has seen WWE's Punk documentary, 'Best In The World', they'll know that the 36 year old is a fascinating guy. Indeed, fans can't get enough of Punk. He's consistently one of the most googled wrestlers online, which should carry over to the UFC. If a Punk interview and documentary was to feature on fightpass, there'd be lots of new subscriptions from WWE fans. Plus, it should be even better than WWE's documentary, as UFC will let Punk be Punk. That means swearing.
