Real bad fight for Tszyu. Pac is too fast and Tszyu's speed and punch selection wasn't dynamic enough IMO to really control what Pac's style brings. Probably a late stoppage for Manny.
Did you see what Marquez's right hands did to Pacman? Now imagine Tszyu. So long as he enters the fight in top condition this isn't a challenge for Tszyu.
Tszyu is stronger and hits MUCH harder and his right hand is way better than JMM's. Pac getting fuked up here.
Marquez is faster and is the better combination puncher. Did you see what Phillips' speed and power did to Tszyu? Easy game to play.
Is hard for me to decide too. In their primes i think Manny is overall a better fighter but he was still developing at 140lbs as a fighter. Plus Kostya's style is pretty dangerous to Manny's who tends to dart in a out. Kostya is pretty good at timing his right hands and may catch Manny coming in. I can also see that Manny just overwhelms Kostya too.
The difference is, although Judah was a speedy southpaw, Pac can take it and fires combinations in rapid fire succession. I see Pac edging it on points due to workrate, as Tszyu is, with the sole exception of the Phillips loss, rawhide tough and very durable.
Pacman's career has been built on: Cotto, ODH, Hatton. All very one handed fighters with awful right hands. Cotto, ODH lefties. Hatton with T-rex arms reliant on jabs and left hooks.
I certainly don't see it being easy but although it's easy to go on about Pac hating right hands,it's the long rights that he really has a problem with and Kostya at his peak could follow up the jab beautifully with painful accuracy. I'll go for Kostya on a MD.Hard for him to outwork Pac and convince the judges but it's certainly doable.
