Tszyus best win was probably against Gonzalez who made 10 or so defences at 135 pounds. Mitchell was a better boxer substantively than Judah. Judah at his peak first time at 140 was dangerous. I dont see this current version of Juda beating alot of guys Tszyu beat. Hes damaged goods, so no, beating Judah doesnt make you great. What was more significant is he unified all three titles. At the time Judah looked to be a killer, in hindsight, there was only ever going to be the same winner in that fight anyway you look at it.
