I could see Jean Pascal being considered should he pull off another one or two shock wins in the twilight of his career. Lost more than he's won at the top, top level but a pretty entertaining fighter with a fairly lengthy resume.

Kovalev.
Jacobs (including his story).

Kovalev is a boarderline one for me, kinda like a Dariusz M (who beat a lot of cans, but also comfortably beat long reigning unified champ Virgil Hill , and some other solid wins). Kinda like Kessler too I guess.
