I'm gonna hold off on saying that it was drug related because I don't think it was drug related personally. My thinking is that maybe his past substance abuse problems may have damaged his body enough for something like this to happen. With his past substance abuse problems damaging his body and the life of a WWE superstar (getting thrown around every night, taking crazy bumps breaking down your body even more, the lack of sleep), I'm thinking maybe something stress related. Call me stupid if you like for my thinking, but either way this is a tragic loss for the entire wrestling world and the Guerrero family. Eddy was one of the only reasons I even watched Smackdown. The man was one of the most gifted athletes to ever step in the ring no matter if you liked him or not. Us as wrestling fans have lost a great performer who gave it his all when he went into that ring. RIP Eddie, you will be missed. VIVA EDDIE GUERRERO!!!
