I don't think so. I don't see Quarry beating Conn or Pastor. On the other hand Quarry against Burman and Nathan are 50/50 fights, so I could see Quarry possibly going 2-0 against them.
Pastor and Conn beat him comfortably. Beats both Burman and Mann. I like Mann's style but I think his chin would fail him in this one. Burman turns it into a slugfest, Quarry obliges and knocks him out in the 8th after a brutal fight.
Too fast and smart for him. Quarry could counter punch sluggers well but he struggled bad with boxers.
I’d pick Conn to beat him due to styles, Pastor is also a boxer but I’m not sure that’s enough to make up for the lack of quality, (not saying he’s not good, but I feel Quarry was a better fighter and enough to overcome the style disadvantage).
Other than Conn, Jerry has at least 50% - 75% chance of beating everybody else. Simply put, Conn is too fast and slick for Jerry. Only way I see Conn losing is by becoming reckless and getting caught just like happened versus Joe Louis. Otherwise Conn outboxes Jerry all the way to an UD, Thus, it should be 3-1 for Jerry. Not bad.
Billy Conn is an all time great fighter and Lt Heavy Champ...and remember kids...George Foreman's brain trusts steered him away from Quarry...they didn't like Jerry's counter-punching. Foreman's people didn't think it would have been a good math-up for George..
