There's a few things to consider. One is the difficulty Marciano had with Walcott over 12 rounds. Another is the success Byrd against Tua. Byrd would be the taller and rangier fjfhter, he'd probably outweigh Rocky on fight anyway. I do think Rocky will stop him because Byrd preferred standing in the pocket out speeding slower opposition, which means half the battle for Rocky is won because that's where he'll want the fight to be. Unless you knock Rocky out you can't fight him in the inside.
Foxy and I got seriously stuck into each other for a short while, and then for some reason he was chilled a few months later. I haven't got any hate mail yet, not even from Dino who I like to wind up from time to time LOL. Obviously I'm not trying hard enough.
Dino is a sucker for punishment. I saw that he was wandering through the lounge, engaging with his flamers, who were only too happy to pile on. Gotta say, the Lounge explains where all the race shyte on these boards comes from.
1. Walcott was hitting Marciano with hard vicious punches. And he was much better than Chris Byrd, and completely different style. 2. That's Tua's problem, not Marciano's.
Obviously Walcott was a far better puncher than Byrd, and a better all-round fighter. Walcott was a solid counter-puncher and hit hard off the backfoot. Watch the fights, I'm sure you know enough about boxing to be able to come to that conclusion. Punching alone gives a fighter a much better chance of standing up to Marciano. Being a light slapper is probably the worst thing. Tua plodded along in a bemused state against Byrd, as if he had all the time in the world or he just resigned himself to it at points. That's Tua's problem. Tua is Tua. Marciano is the last fighter in the world you'd figure to be undone like that.
Anyway, Marciano KO'd Walcott in the 13th round and said afterwards "I thought I was a hair behind so I knew I had to do something". The idea that he'd let Byrd slap and prod him around for 12 full rounds without doing something about it is silly anyway.
