I don't see the correlation, I mean maybe it's just these fighters that appeared on their cards recently that just happened to use more PEDs or they are really just more rigorously tested.
But an intentional foul play? Why? Baumgardner, Cusumano, Whyte, Benn, Helenius
There is no pattern that would suggest they fukk those who went against them or something. Some of these were really painful to them like Whyte, Benn or even Baumgardner, and others like Cusumano and Helenius... MR had just no reason at all to fukk them. So I don't think it's foul play.
I also don't think they intentionally hand out PEDs to their fighters, if anyone is doing that those are trainers, SnC coaches and whoever is involved in the preparation of a fighter.
