nice read but I hope people don't actually think in the 70's you would walk into a gym and see guys that looked like Mentzer and Arnold everywhere. guys at that time were way smaller than guys are today, but because of videos people think those were the norm.
those of you who have that mentality that the 70's had bigger men are just old I guess. if you took the best NFL team today and put them up against the best team in the 70's the score would be 100-0. and if you took a typical meathead gym today up against a meathead gym from the 70's it wouldn't even be close.
the average size of Olineman entering the NFL today are 50 pounds heavier than they were in the 70's.. even QB's are 15 pounds more and WR's are 15 pounds more too
more people lift weights today than did in the 70's, gyms weren't even available unless you lived in a decent sized town/city or they were hole in the wall places. high school kids are even as big today than the pro's were in the 70's
