1. Breidis - by far the most durable, tough and powerful fighter Usyk faced at cruiserweight. IMO Breidis beats all of Usyk's remaining cruierweight folks. 2. Hunter - excellent all round skills. Went on to beat Bakole at heavyweight later. 3. Gassiev - hasn't done too much since but was a tough hard hitting fighter in his day. 4. Huck - past it but dangerous 5. Bellew - past it but again dangerous
Briedis Gassiev The rest I would have to think about so I haven't put them in order here Glowacki Huck Hunter Bellew Mchunu Were all current or former world champions Breidis Gassiev Glowacki Huck Bellew Mchunu should of won a world title and was clearly robbed of achieving that Hunter was easily good enough to become world champion but he moved back up to HW All undefeated Briedis Gassiev Glowacki Hunter Bellew was undefeated at CW/HW 10-0 (8 KOs) Were murderous punchers Gassiev Briedis Were all KO artists or legit bangers Glowacki Bellew Huck Hunter Mchunu could hit a bit too and his KO 56% was a little deceptive as he fought a lot of very durable and durable guys Anyone who cites an inactive Gassiev losing to Wallin 5 years later after being wracked with injuries and surgeries and not having fought anyone with a pulse in all that time, only fighting like 4 times in total in all that time against tattoo artists, street vendors, crab fishermen and shepherds doesn't get taken seriously. Prime Gassiev was a monster at CW and one of the hardest punchers in the sport in recent memory
