Actually you're the revisionist. I watched boxing back then but the HW competition level was very, very low. The best guys prime Tyson fought were a very undersized Michael Spinks and an old, fat Larry Holmes who joked about coming in out of shape and laughing all the way to the bank as he collected his paycheck. Put Mike in the 1970s and make him consistently fight Ali, Frazier, Foreman, Shavers, Norton, Lyle, etc. and you'd see very different results. In fact, Foreman and Shavers returned to boxing in their 40s because they both thought Tyson was beatable.
