He didn't serve when called, took what America had to offer and didn't even leave a dime on the counter, Great Boxer Yeah, Great American NO.
I agree with Brad. But with that stated, coming from a boxing family, and having lived the fight world since the early 1950's, I know the personalities of many of the greats. Ali became a better person as he got older. In the late 90's I was in a limo with Ali when he was picked up at an airport to be taken to the Boxing Hall of Fame ceremony. He was gracious and funny. It was the third time I had met him.
I met Joe Louis back in the 70's. And in my opinion was the greatest of all. He was a gentile giant. His knock out punch was only 6 inches. He had an infectious personality.
I met Rocky Marciano a few times and a few years before he died in the mid 60's. I was a teenager and Rocky, along with Joe Louis and a few others were my idols. Talk about taking a punch. He literally had a steel jaw. Rocky was an under-rated fighter. He to had a super personality. Also met Frazier, great fighter but who was a jerk. Ken Norton, and of course Foreman were also classy and great fighters.
Carmen Basilio was a family friend. He was a welterweight, and middle weight. Pound for pound one of the toughest fighters ever. Sugar Ray Robinson, I met also. Sugar Ray has been called the best fighters ever.
I met Mike Tyson when he was inducted to the Boxing Hall of Fame. He can be classy, he can also be a real jerk. As we know. I can go on and on.
Many of the old time fighters never got the publicity from TV like in the modern era of boxing. Ya, there were the Friday night fights. But, only a few of the fighters were shown. If the boxers of the 50's and 60's had the TV coverage, like Ali, Ali's stature of being known as the greatest would have more controversy.
Yes, Ali was great. But not the greatest, especially in his weight class.
