Frank and Ken Shamrock aren't exactly close. The two brothers have never gotten along that well and since the death of their adopted father the rift has grown.
"Ken and I are just two different people," said Frank Shamrock. "We don't really have (a relationship), we never have. After Bob (Shamrock) passed there was some resentment there on his part.
"But, I've never had a heart to heart conversation with the guy. He was never available and I was never a good communicator. We were too guys that never got past working out together. It's totally bizarre. I know more about the guys I train with today than I've ever known about Ken. I think when we were younger Ken was a very closed off dude and I wasn't a good communicator. Now, that's changed for me and Ken's changed as well but we never grew together." LINK
