Steve Haaas, Occidental College in the early 60s had bests of: (school Records) of 9.4, 20.7, 46.9 and 1:47.6 but couldn't break 4:00. His 1:47.6 trumps all of Johnson's shorter races and demonstrates superior endurance. However he still was shy of the guns necessary to run 4:00. This thing has been traveled before and just because some runs fast at lower /lesser distances it doesn't necessarily mean fast farther. Lee Evans and Tommie smith used to run 10 miles a day at times. That translated to faster 400 times. While more mid-distance guys are running it 4:00 is still a challenging mark to achieve.
EPO didn't exist in the early 60s. Well, not synthetic EPO that is.
How does 1:47.6 trump Johnson's shorter races? I'm not sure I understand that.
