Lets make it 15 rounds to split the difference slightly against Jeffries. How would he do against Lewis's versions of: Gollota Hollyfield Grant Tua Ramhan Tyson
Golota would find a way to lose. Grant just isn´t a good fighter. Tyson would be too much past it but at least has a chance early on. The others beat him. Under the rules of Lewis´time. Under Jeffries´ rules with fights to the finish, he beats them all. Tua has the best chance here, I think. Doesn´t make much sense IMHO. How do you want to judge how Jeffries does against them? He basically fought in a different sport.
They would all beat him, technically they are all better, most had the jab to control him and outbox him, most would be defensively better, most hit harder, most are faster, all would have better jabs and Jeffries has no size advantage. His vaunted chin/durability would no longer exist because he'd be getting smashed by much bigger men
Rahman, Grant = **** Golota = born loser Tyson = a faded crackhead by the time Lewis fought him Holyfield of 1999 and Tua were decent.
