Tyson Fury needs to defeat more of the heavyweight division to "cement his greatness", so says Shannon Briggs.
WBC champion Fury is eager to return to the ring by early 2022 following victory over Deontay Wilder in the trilogy fight between the pair in October.
But his opponent remains unclear as uncertainty lingers whether he will face Dillian Whyte, who wants to be sanctioned as the mandatory challenger for the heavyweight title.
Fury also has his eyes on a bout against Oleksandr Usyk, who claimed the WBA, WBO and IBF titles from Anthony Joshua in September.
Usyk and Joshua are set to meet again in the early months of 2022, though the latter could drop out to allow the undisputed fight and Briggs believes Fury needs to face top contenders to cement his legacy.
"I think he'll make the decision to stick around and fight guys," Briggs, who was a two-time heavyweight champion, told Stats Perform.
"He's not very old, although he's accomplished a lot. He's had gaps in his career between lay-offs due to whatever circumstances he was dealing with. It hasn't been consistent.
"I think that for us to cement his greatness, we need to see consistency. I think we need to see at least three to six wins from the guys in the top 10.
"Clear out the top 10, clear out the heavyweight division, and then maybe we can say he's the greatest heavyweight of all time, due to size, due to his ability to move, his rhythm. For a big man, it's just unreal.
"His heart, his chin – he got off the ground against one of the hardest punchers that ever lived in [Deontay] Wilder."
The undefeated Fury has 31 wins to his name, with the only blotch on his record a contentious split-decision draw against Wilder in their first clash.
Briggs appreciates the talent of 'The Gypsy King', who he implored to become more consistent to further his standing within boxing's history.
"He's shown us flashes of greatness, but we need to see one last thing," he added.
"What makes a champion is consistency, so we need six to 10 Larry Holmes style wins, Lennox Lewis style wins, staying busy. Lennox was a busy fighter. Lennox defended his title, he fought a lot.
"We need three, four fights a year consistently for the next two years if not more. I think he's a great guy and a great fighter, but I just think we need to see consistency and consecutive wins."
