As a european myself i'm gonna be rooting for all of them, but i think it's most likely gonna be Khabib. His pressure and wrestling ist just from another planet, but pettis is almost a complete fighter right now. if he's really focussing on wrestling and askren is there for him all training camp it's a toss up.
I really hope the Conor Hype continues, but i don't think he's gonna beat Aldo. Unfortunately
Gus has to beat Rumble first, i'm not even sure if he's able to do that. In a rematch with Jones he's gonna get crushed. I think Cormier is still the second best LHW out there and i belive the storys about Jones was overlooking Gus for their first fight and now he's gonna proof it shouldnt be that close in the first place
