Now, seemingly all of a sudden, the middleweight division is the most exciting division in the UFC. Weidman, Belfort, Rockhold, Jacare, Machida, Bisping, Tim Kennedy, Alan Belcher...and likely Anderson Silva again one day. It seems like just yesterday the division was stale with Anderson sitting at the top and no real threats to him.
The only other division I would put above it right now is 170.
