This Scot was an isolate success like Borzov for USSR and Eugen Ray for GDR. Wells won the Olympics, so did Borzov, but only Borzov (1971 & 72) and Ray (1977) were ranked #1 in the World by Track & Field News.
As for Moscow, Aksinin and Muravyov were in the final. Ray, 10.30 in quarter final, was disminished by injuries and didn’t get through the semis. The other GDR guy Schlegel ran 10.28 in the first quarter final but placed only six as this race, won by Wells in 10.11, was packed with many big names (one of the many scandals during these Games?), and Schlegel and defending Olympic Champion Crawford (10.28 as well for 5th place) didn’t advanced. Mennea, 4th, barely qualified with 10.27 for 4th place. Mennea and Quarrie, who would eventually get gold and bronze at 200m, ran baddly in semis (10.58 and 10.55 respectively) and didn’t advanced to the final. Note than 10.39 was enough to get bronze in final.
