Arch Jelley queried aloud, why hasn,t someone approached 139?
this was in 1977.
Arch was John Walkers coach, who predicted Walkers WR, when his PB was 338, which came true except Bayi broke it as well for the win.
meaning coached now and then really dont think 139 is out if reach.
really back in the day they were running 143 144 with suspect training, nutrition, and suboptimal tracks, but the athletes themselves, may have had better talent than today.
because there were not megabucks in pro sports.
