A sure fire lock to make my list, if this was a list of favourites he'd probably be top 10.
The 73 Mascaras match is my number one match of the 70s, and the 69 Baba match is a masterpiece.
One of the all time greats at talking during a match. Whether he's barking at the fans, berating the referee, shouting at his opponent's seconds, he always knew when to throw some character work in while doing something simple like working a hold.
I havent watched any Dr X stuff yet, but checked out some of his pre mask work and he seems like a guy that just 'gets' wrestling, whatever role he is in.
