Gz vs. Aoki is an integral match-up. If the winner of that match wins the whole tournament im ranking them #2.
If kawajiri, ishida, or sakurai win the whole thing and face aoki or GZ in the tourny then i would put them at #2 as well.
And more than likely if even a nobody in this tourny wins the whole thing and faces stiff competition the whole way through then i would possibly put him in the top 3 as well.
IMO gomi and sherk do not deserve the #2 spot.
Sherk has never defeated a top ten fighter, ever.
Toughest competitor he's defeated at Lw is Kenny Florian.
and by no means am i beashing him, but he wasnt (and isnt) a top ten LW.
Gomi hasnt looked all that great recently, against ludwig he looked to be getting into top form again but he didnt have to worry about takedowns or subs.
If he can perform at his best against a well rounded fighter then i think a top 3 spot has merit, but until then... no way.
