All time or current? Current Loma Rigo Andrade Ward possibly Usyk but I need to see more of him. Past Pea Whitaker PBF Hearns RJJ
All time: Joe Frazier, Henry Armstrong, Roberto Duran, Aaron Pryor are good examples. Now, I'd say Wladimir Klitschko is still extremely difficult to out-box. In his prime, he was almost impossible to out-box I reckon. You'd have to knock him out to beat him, you're not going to out-jab him or any of that ****.
No, I don't think so. But he certainly out-fought and out-worked a very very good Duran. De Jesus was twice knocked out by prime Duran.
When I think of " out-boxed", I think of winning a decision and Duran lost decisions to de Jesus and Benitez, not to mention Laing, Hagler and Leonard, and he was having a tough time with Buchannon. The Viruet brothers also fared pretty well against him. Duran is one of my favorite fighters and he is definitely top 10 in my book. However, he could be "out-boxed" imo.
Vitali Klitschko. He was never behind on the cards in any fight he competed in as a pro. In other words, NOBODY outboxed him. He was always ahead in all his fights.
So if a pressure fighter wins a decision with work-rate and pressure, you see that as his out-boxing his opponent? Buchanan, DeJesus, Leonard, these are some of the best guys who tried to out-box him and failed in his prime. By your criteria though, Duran was easy to outbox; hell, Omar Gonzalez managed it.
