No, there are plenty of guys who are overrated to the moon and back. Gassiev is rated rightly I think. Good fighter with a solid resume and a nice run in WBSS. In order to be overrated you first have to be talked about and Gassiev hasn't really been talked about in a while. He just had the misfortune of meeting Usyk at the absolute prime of his powers coupled with being unable to deal with southpaws too well (plenty of ATGs hated fighting southpaws though, not that Gassiev is an ATG mind you).
He´s finally 30 now. And boy has he underachieved. He was only 24 at the time of the Usyk fight and has only fought 5 times since. What a shame, a wasted career.
You use word overrated here to often. He was great Cruiser who beat Lebiediev, destroy Włodarczyk, and destroy Dorticos. He is for sure not overrated... His career stopped because injuries. When health said "STOP" its game over. He probably also should try his chance in bridgerweight first before HW. He got power for Hw but his weakness is footwork and speed movement. That's because he lost to bigger Wallin on backfoot and that because Usyk beat him easy. But still his power + skills, hand speed and chin make problem for many, many dudes. Just give him when he is healthy somebody who go forward and You will be shocked probably.
He was an absolute beast of a Cruiserweight Does not look the same guy up at heavyweight, probably cause of all the injuries. Yet still I had him winning against Wallin, Wallins tippy tappy punches were **** all.
