Another reason why I think the 100 Fly was more impressive is because in 1974 at the NCAA Championships Robin Backhaus went 1:47.04 in the 200 Fly and missed the record by .15 and the next year in 1975 he missed it again going 1:47.16
That 1:47.04 time is still the men's record at the University of Washington, by the way. Backhaus also still holds the record in the 500 free with a 4:22.91.
