People will bring up their amateur record, but ultimately Jalolov was young and not too successful all the times they fought. He went on to get better and have a far better amateur career than Dychko. I'll say that I haven't done much film study for Dychko, but I've watched his fights vs Zhang. He definitely seemed weak to southpaw lefts, but it's hard to say because even back in the day Zhang was very accurate and deadly with his lefts. Dychko was hurt badly in both fights, though, so he doesn't have an invincible chin or anything. Zhang was much lighter back then. He was probably about as light as Jalolov now. I think Jalolov would hurt and maybe stop him based on what I've seen from both of them.
I just got Dychko there for now. I think he goes through with his right and cracks him Jalolov is good, but very basic. He's got his footwork and he's always doing just 1-2 and left to the body He is a better version of Wilder And his chin is absolutely unproven. He barely get hit in fights (I think Jack Mulowayi hit him zero to the head in 8 rounds, thats crazy), so we don't know anything about his chin
Jalolov (when he finally found his form) benefited from a weaker super heavyweight era after 2016 .when Majidov, Dychko, Cammerelle, Joshua, Yoka, Hrgovic, Joyce, Zhang had all turned pro. (and Cammerelle had retired) Dychko fought amongst all them and still medalled multiple times in every major tournament. Whereas Jalolov has had virtually no competition in the much weaker era after that Joe Joyce pummeled Jalolov all around the ring with ease, Dychko beat Jalolov 5 times, and Kunkayev stopped him him in the first round. My money would definitely be on Dychko
