HW= Needs work. They have some up and comers, but they need someone who can challenge NOG now.
LHW= All the best LHW fight in the UFC. It is absolutely stacked.
MW= Very hard to tell that they have so many great MW, because Silva keeps destroying them all. Outside of Lindland and Lawler their not missing anyone, since WEC is planning on closing down their MW division, and Filho will soon be in the UFC.
WW=Possibly the second best division in the UFC. It is stacked from top to bottom. Shields is really the only guy I think they need.
LW= I agree they do have great fights in this division, and they have the #1 LW in the world. They don't have a majority of the best fighters in this division. Gomi, Alvarez, Hansen, Aoki, Kawarji, Thomson, and Melendez all fight outside of the UFC. This is why BJ wants to move up to fight GSP. There is no challenges left for him at 155 in the UFC.
