Leon and Michael Spinks at the U.S. Olympic Trials, on June 6, 1976, in Cincinnati, Ohio.
Sports Illustrated's article, from June 14th issue, on the trials put it mildly (their caps, not mine):
AFTER THE LAST BELL CLANGED, CONCLUDING THE HARD-FOUGHT OLYMPIC TRIALS IN CINCINNATI'S RIVERFRONT COLISEUM, THERE WAS NO DOUBT BUT THAT THIS COUNTRY WILL BE SENDING A BALANCED, FORMIDABLE TEAM TO MONTREAL NEXT MONTH
The author, Robert H. Boyle, added:
"The strength of the team is the result of a quiet resurgence of amateur boxing in the U.S. Half the contestants in the semifinals in Cincinnati got their start in a Junior Olympic Program that Roily Schwartz, the team manager and National AAU boxing chairman, helped form several years ago."
In the finals Ray Leonard won a decision over Bruce Curry.
SI added:
"Predicting medalists in Olympic boxing is a chancy business. Besides Leonard, regarded as a near cinch for the gold, there are other hopefuls among the winners at Cincinnati. These include 125-pound Davey Armstrong from Puyallup, Wash., a Pan-Am gold medalist, and 132-pound Howard Davis, of Glen Cove, N.Y., who won a gold in the 125-pound division in the world competition in Havana in 1974. Davis moved up in weight for the Trials and defeated Aaron Pryor of Cincinnati, the nation's top-rated amateur lightweight, in a rousing final."
Clinton Jackson from Evergreen, Ala., who fights out of Nashville for Ace Miller, won the 147-pound competition. The only boxer ever to win three straight National AAU and Golden Gloves titles, Jackson was named the U.S. Olympic athlete of the year in all sports for 1975."
More from the SI article:
"Leon Spinks of St. Louis, a Marine lance corporal stationed at Camp Lejeune, N.C., won the 178-pound title. He was a bronze medal winner at the World Games in Havana and a silver medalist at the Pan-Ams in Mexico City last year. His brother Michael, not as highly rated, won the 165-pound championship, and their joint victories mark the first time brothers have won in the Trials."
