The problem is that they need longevity with a half decent win/loss record if they want to eventually get a money- making title fight.
Otherwise, big money fights usually only come to undefeated or close to undefeated fighters. There's too many hard punchers that can distort your record if you fight the way that Rocky fought- take 2 or 3 punches to give 1 of your own.
He was one of the best though.
I think that they recently released the computerized/simulated "fight" between him and Ali.
They say that the fighters had to follow the choreography developed by the computer. Blows to the head had to be pulled but anything went when it came to the body.
Ali was knocked out in the 13th.
Ali was pissed. LOL!
