Mike Katz is not even a pro. He's a top amateur bodybuilder
Actually, he is (or was). Despite his well-documented disappointment of 1975, shown in
Pumping Iron, Katz went on to compete in the Olympia in 1976. However, much like the '75 Universe, he would fall at the hands of Ken Waller, who won the 200 lb.+ class.
He would also compete in the 1981 Mr. Olympia, where he placed 15th.
