Yes one round. I feel Tunney is very overated as a heavyweight and as a boxer in general. He wasn't as skillful and clever as people tend to think of him, and neither Lewis nor Tyson will have anything to fear from him, and will finish him shortly.
What never happened is Tunney facing a super heavyweight. It's much different to run from a slow far past his prime Dempsey, who, in addition, desided to change his rushing style to cautious boxing, from attempting the same vs quick super heavyweights in their prime, he won't last a round.
Lewis wan't "super quick" on his feet and certainly wasn't quick enough to out manuver Tunney who is 2nd only to Ali in terms of Foot speed.
You probably haven't seen enough Lewis. I have all of his pro fights, except one. He could be very quick with feet and hands.
Tunney was overrated as a Heavy in the 80s no doubt (I had him #7). But as the 90s came people spoke more of his non Heavyweight work and thus over the last 20 years he has become probably underrated as a Heavy (I now have him at #21)...
Would not last a round? Tunney had excellent foot speed, was a master of distance, and could stick a guy with his jab or right hand. Tunney was only floored once in his entire ring career. While Dempsey was older, he was not slow for this match either.
Where was Tunney's "excellent" foot speed and defensive mastery against not too far past his prime Greb? Where was it against green Loughran? Maybe against Jim Delaney? Where was his jab against these fighters? He forgot how to box against them?
:yep Literally, all of those big, skilled heavy punchers post-Louis era are going to remove Tunney very quickly, ESPECIALLY Tyson of all people. It's absurd that some of these people equate a past it, primitive Jack Dempsey>Prime Tyson.
tunney is underappreciated although i think he has trouble with all of these guys. he will probably win on points against jeffries and foreman though.
