When I started on Sheridan's path 15 years ago, I thought I'd write about it someday, but I never got past a single short essay I posted on my web page.
Sheridan studies muay thai (kickboxing) in Thailand, boxing at Harvard and later in Oakland (with Andre Ward), MMA in Iowa with the Miletich camp, and jiujitsu in Brazil (with BTT). He also travels to Tokyo with Antonio Rodrigo Nogueria ("minotauro" -- former Pride and current UFC heavyweight champion) for his decisive encounter with Fedor Emelianenko.
Sheridan's insights and writing are good. The only problem is the guy has no ground game, so he writes about grappling -- the real heart of fighting -- like a mere journalist :-)
