He wasn’t a really good boxer in terms of technique, but he had the home run punch. Sometimes it landed.
I think he would have been only a few notches above club fighter if Ali hadn’t picked him as an easy opponent in his waning years. Terrell was better than he thought—or Ali had faded more than he thought—and then his reputation was made.
In a way, he’s the Black Rocky.
I believe that you are thinking of Earnie Shavers...Ali carried Terrell for 15 rounds and beat the snot out of him...
