I think I would have to say, The Monster, Beterbiev and Jaron Ennis, even though he is technically still a prospect.
Inoue isn't necessarily as hot as a prime Virginia Madsen. But he's hot. Let's just say that. He's hot enough that they're in my mind at the same time. And that's quite hot.
Exactly and always figured out ways to not fight fought eliminators (ex. Derevyanchenko at 160, Korobov at 154) or tough fights in general (ex. Jermell Charlo at 154).
Vergil Ortiz will soon become (if he's not already) a boogeyman for the likes of Spence and Crawford. Beterbiev has been the boogeyman in his division for awhile. Hrgovic i'd say is somewhat of a boogeyman as boxers like Hunter (ducked Hrgovic to fight a bum on triller) and others refuse to fight him. Some fans think David Benavidez is a boogeyman but i'm not sure i buy the hype. Golovkin was considered a boogeyman for years when he knocking out everybody.
I know it sounds a bit silly but it's still Golovkin. Why, you might ask? Well, because the so-called pound for pound king ' Ginger Clenelo ' has refused the biggest fight in the sport for years. A 3rd fight with Golovkin.
Id say Beterbiev. Hes had some big fights fall through, and has not had his signature fight yet while holding 2 of the light heavyweight trinkets! If anybody will give him his signature fight though, it will be Canelo.
