B level fighter because he lost to guys he can't beat like Wilder, Jarell Miller??
I don't know much of this Washington guy, but looking at his record i don't see some bad losses. His only loss that makes him look bad is to Charles Martin, yet Martin stopped Glazkov (although by an injury) but still.. These are all the top dogs of today.
And where have you seen Helenius beating ''Finnish gatekeepers''?
I see a very wide range of victims and not one of them finnish - he beat Turkish, German, Russian, Belorussian, Georgian, UK guys.
Probably one of the most diverse resumes I know of.
Aside from that he has lost to only Dyllian White and Johan Dahaupas. It doesn't look bad to me.
