That a square of a yard be chalked in the middle of the stage, and on every fresh set-to after a fall, or being parted from the rails, each Second is to bring his Man to the side of the square, and place him opposite to the other, and till they are fairly set-to at the Lines, it shall not be lawful for one to strike at the other. That, in order to prevent any Disputes, the time a Man lies after a fall, if the Second does not bring his Man to the side of the square, within the space of half a minute, he shall be deemed a beaten Man. That in every main Battle, no person whatever shall be upon the Stage, except the Principals and their Seconds, the same rule to be observed in bye-battles, except that in the latter, Mr. Broughton is allowed to be upon the Stage to keep decorum, and to assist Gentlemen in getting to their places, provided always he does not interfere in the Battle; and whoever pretends to infringe these Rules to be turned immediately out of the house. Every body is to quit the Stage as soon as the Champions are stripped, before the set-to. That no Champion be deemed beaten, unless he fails coming up to the line in the limited time, or that his own Second declares him beaten. No Second is to be allowed to ask his mans Adversary any questions, or advise him to give out. That in bye-battles, the winning man to have two-thirds of the Money given, which shall be publicly divided upon the Stage, notwithstanding any private agreements to the contrary. That to prevent Disputes, in every main Battle the Principals shall, on coming on the Stage, choose from among the gentlemen present two Umpires, who shall absolutely decide all Disputes that may arise about the Battle; and if the two Umpires cannot agree, the said Umpires to choose a third, who is to determine it. That no person is to hit his Adversary when he is down, or seize him by the ham, the breeches, or any part below the waist. A man on his knees is to be reckoned down.
Tyson. He has enough concussive power to knock Marciano out for a 30 count if he lands correctly, great body attack, he has superior head movement (a very important consideration without gloves) and his shots are crisper and shorter--fewer winged punches = fewer chances for a hand breakage. The start-stop rhythm of LPR may work to his advantage compared to Queensberry, as he was always at his strongest in the beginning of a round rather than the end.
Tyson had no heart. He folded against Holyfield and Douglas when he was pressed. In a 15 round fight I think Rocky brutalizes Tyson if it goes past 5 rounds. I think Rocky survives Tyson with ring savvy and heart in the early rounds and then brutally knocks Tyson out in the 9th round. Don’t forget that Rocky was in the ring with Walcott, Charles and Moore and those guys had heart and way more championship rounds than Tyson ever had. You cannot name one fight that Tyson ever had where he had to dig deep to pull out a win against a top ranked opponent. Rocky had a career of winning the big moments in the most difficult circumstances. FYI: Mike and Rocky were American boxers so they would have to fight under our rules.
