Vic Darchinyan gets my vote, his style is very awkward, but also very effective, just look at the destruction he did to Victor Burgos, he damn near killed him!
i'm french i don't realy understand what awkward means, can someone explain me please
Awkward: lacking dexterity or grace in manner or movement or performance.
Merqui Sosa was pretty damn awkward.
Zahir Raheem is pretty awkward. He seems to confuse everybody he fights and also frustrates them because he ties up. He's so awkward I hate watching him.
I saw him on FNF a few years back. He was an Asian fighter, maybe Japanese? But anyway, he had this style where he would jab and then immediately would follow the jab by coming over the top with a "windmill" punch. 1-2, 1-2, for the entire fight. It was an odd, but interesting style.
