Would Tarver, Bivol, Beterbiev, and Roy Jones be top 10 heavyweights during Joe Louis's era

Two answers to this question

A)No if we list everyone in the era.

B)Yes if we consider circumstances. Top fighters were retiring early, going to war and Rings rankings were erratic. They all would have been in the top 10 at some point. They are all better than Lee Savold who made the top 5. I argue Lee Savold was not top 20 in his era but he still got into the top 5. He wasn't the 5th best HW when he had that rating but he had it.

 

Yes, they’d each have their moments as no. 1 contenders but they’d also each get battered by Joe.

 

Yes

 

Yes. Especially RJJ. RJJ as we know him would certainly be the light heavyweight champion and would likely do what other top light heavies of the day did and that is, set their sights on the heavyweight championship. Instead of Conn vs Louis, the public would be demanding Jones vs Louis.
