There has been a lot of movement in the lightweight division as of late, and not only because of fighters that have lost. No, Clay Guida and Frankie Edgar have decided to drop to 145, and now have effectively been dropped off the lightweight rankings. Big matches to look forward to in early 2013 are Matt Wiman vs. TJ Grant, Diego Sanchez’s return to 155, Gilbert Melendez vs. Benson Henderson, and Donald Cerrone vs. Anthony Pettis.
#10 Shinya Aoki
He may not have the biggest wins in the last year or so, but since his return to lightweight in 2009 he has gone 12-2. His only losses come to top ten fighters Eddie Alvarez and Melendez, and he has finished 9 out of those 12 wins. It is hard to gauge how well Aoki would do in a big promotion like the UFC since he is content to fight in Japan or One FC, but with wins over Antonio McKee, Rich Clementi, Lyle Beerbohm, and Satoru Kitaoka, Aoki is definitely a top ten lightweight.
