Jack McGann: From Cage to Ring

Shamrock: Bound by Blood, a gripping 65-minute documentary that airs Thursday on Spike (11 p.m. ET), stirs up a few ghosts still haunting the MMA personality. There's a lot of story to tell (Spike producers said they bandied the fighter's 2012 memoirs around the office to begin), but wisely, Shamrock focuses mostly on Frank's deteriorated relationship with his iconic brother Ken.
