I agree , Ali did more than just boxing, There's a couple of bits on youtube and one were Ali talks about Sugar Ray and gladly says "If we are talking about pound for pound and not a heavyweights then Ray was the best boxer that ever lived".
Ali even asked him to manage him, Ali brought thats glitz and glamour after seeing a wrestler Gorgeous George get booe'd and he said that a good idea, they all paid in to boo him
