#4. Former UFC title challenger Marvin Vettori
Former UFC title-challenger Marvin Vettori could insert himself into the top-10 should he move up to light heavyweight. Although he has only received one title-shot, he does have two losses against reigning champion Israel Adesanya. He could reach a point where a move to 205 lbs could be his only path to a title shot.
Vettori's most recent fight was contested at 205 lbs after his opponent, Paulo Costa, was unable to make 185 lbs. Despite Costa's fighting at a heavier weight, Vettori still managed to absorb heavy shots and earned a unanimous decision win.

'The Italian Dream' is 8-3-1 since joining the promotion in 2016 and has been praised for his durability. He's currently the No.3- ranked middleweight and is scheduled to fight former champion Robert Whittaker in September. If he wins, there might not be many appealing options at 185lbs, so a light heavyweight move could be enticing.
#3. Former UFC title challenger Jared Cannonier
Former UFC title challenger Jared Cannonier is no stranger to competing at light heavyweight. Prior to moving down to 185lbs, he competed at both light heavyweight and heavyweight. His losses at light heavyweight came to top fighters in the division like Dominick Reyes, and former champions Jan Blachowicz and Glover Teixeira.
Despite having a 2-3 record at 205 lbs, it's important to note that he has improved significantly since then. Cannonier is coming off a title fight loss to Adesanya, so perhaps another attempt at 205 lbs could be realistic. He is 38-years-old, so he would be looking for the biggest fights possible at this stage of his career.
'The Killa Gorilla' has been an exciting fighter to watch throughout his career. 10 of his 15 wins have come via KO/TKO. Taking into account the improvements he's made, it would be interesting to see how he'd fare if he returned to 205 lbs.
