Some of the WWE can't be choreographed

For those of you into the sort of thing, WWE wrestler Eddie Guerrero was found dead in his hotel room on Sunday night. While I am not a follower of pro wrestling, I do occasionally tune in to watch the big guys throw each other around and show off. Eddie to me was kinda cute in that pocket-rassler sorta way. I just never got into the too-involved backstories and whatnot. Just gimme big guys beating each other senseless and shoulder-pressing one another for reps and I'm fine with it. Make you wonder what happened to the guy (an autopsy is scheduled). Was it injuries, his past drug abuses, steroids, unknown health issues, or ?
