They can bring Gafencu, Lambagiu and Stefanovski, at 77-85 kg. Gafencu is spectacular, Lambagiu has very nice body shots, Stefanovski is Swiss-Macedonian with very effective boxing. All are young. Lambagiu and Stefanovski are almost U23, they are both 24 years old, fought for belts same as Gafencu (27).
Stefanovski fights as a journeyman and has lost some decisions, but KOed Beni Osmanoski in Switzerland when it was needed. Osmanovski was close to Glory level or even Glory level at some point. Though poorer than Yoann Kongolo. But honestly all Kongolo, Stevanoski and Osmanovski fought in Superkombat, and Stefanovski is not less technical than Kongolo. Plus Jamie Bates also fought in Superkombat, and if he fights any of these 3 I am not sure he takes it. Bates was KOed in his England by Șchiopu at some massive Romanian event, and Șchiopu has been always just remembered as the sparring partner of Andrei Stoica.
And Bates just beat Harut Grigorian. Hemmers & Co made some questionable fighters champions. Not that they were not challenging material though, but could have lost and still received chances. Others were fired by Glory or not brought.
Surely ONE is not capable of acquiring all the best fighters outside Glory, I cannot see them signing more Romanians after Andrei Stoica, Bogdan Stoica and probably Raul Cătinaș.
There are fighters from China too, etc. For example Levin will be 34 years old in December, not sure if they should bring him or not.. If he agrees on lower purses and if he is at the same level, because you decrease more besides the HW division as stamina!
