Jimmy Ellis wins the majority design. Ellis-M Dec 15

I have heard since this fight that Jerry Quarry had a cracked vertebrae in his back before the start of the fight which slowed him down. This wasn't a very aggressive Quarry which is very rare, but Ellis has underrated punching power which might have made Jerry think twice about coming in fast. Jimmy Ellis was the champion of the world, or at least 45 states. There were some boxing councils that thought Joe Frazier was the real champion and they would have a chance to settle the score in the future. Jerry Quarry never got another World Title fight although he was a top 5 heavyweight for the next 7 years. I really think Quarry was the better fighter, but styles make fights and Quarry never got inside enough to tire Ellis out.
