Ah, starting to jog some of the old memories again about watching wrestling on the WOR tv station! I was too far east to receive the Toronto and Buffalo feeds but sure did watch it on channel 9 . . . although, I hadn't realized it was on at midnight then.
It would have been awesome to watch the NWA back then with that line-up! Instead, we saw some decent mid-card talent such as S.D. Jones, Baron Mikel Scicluna, Ken Patera, Mil Mascaras, Johnny Rodz, George 'the Animal' Steele, etc but nothing like what they had in the NWA. For some reason, I even remember referee Dick Worley and announcer Gary Michael Cappetta.
In regards to the height/weight of wrestlers, I believe they were deliberately distorted to give them the aura of being 'larger than life.' McMahon did this especially with his dinosaurs (credit to the Hitman for that reference) like Andre, Gorilla Monsoon, Haystacks Calhoun and Hogan. I think he tried to carry that illusion out as long as he could at least until Triple H, Nash, Scott Hall and Shawn Michaels had their curtain call at MSG.
