I see Atlas helping Povotkin a LOT with his huge baggage of experience and for having worked quite a lot with big guys. The only way I see Atlas hurting Povotkin is if they get a beef because of money and something, there I could imagine Atlas bursting his bubble and pulling a gun at POvotkin and threatening him to shoot or something.
As for marshmallow man Peters, he'd better start to finally be in a great shape with good conditioning or he'll get brutalized, humiliated and will sink as deep as it can be allowed to in the rankings once and for good.
