John Dino Denis, a sprightly 74-year-old recovering from knee-replacement surgery, shares his memories of training and boxing with the legendary Muhammad Ali. Denis, a former professional boxer with a 45-5-2(20) record, reflects on his two exhibitions with Ali in 1972 and 1979. He describes Ali as one of the greatest heavyweights and fighters ever, praising his speed, agility, and showmanship. Denis recalls a particularly intriguing offer from Ali to train with him full-time in Deer Lake, which he ultimately declined due to his fear of leaving his hometown. Denis also mentions Ali's impact on his career, including his memorable interactions with Ali during his fight with George Foreman and Ali's Asian tour plans. Denis expresses his admiration for Ali's skills and believes he would have dominated Mike Tyson in a hypothetical match. He concludes by emphasizing Ali's greatness and the honor of speaking about him.
