no berbey is not proven at elite level yet. only an elite can kill another elite, have u not seen Ninja 3:The Domination? although to be tru elite u must beat another elite, so maybe 3G isnt one yet (though he will be).
He beat Canelo at least once and Jacobs may not be elite but he's top class, he almost fought Pirog too so its hardly like he was avoiding the best challenges at MW as much as the rest avoided him cmon now.
i mean true elite, not "maybe". but the draw yousuggest is some evidence yes. However trust me, these will all pale in significance to what he will do next to seal his eliteness. Trust me, keep watching.
u will be shocked then by what he does next, truly you will. you heard it here first, dont come crying to me when you see it.
