Although I think Aldo is slightly overrated compared to guys like Jones, GSP and Silva. He certainly is the best in his division, but not quite as impressive and seemingly unbeatable as the other p4p champs. He sort of squeaked by Florian, Edgar and Hominick. He won all of the fights, but he also looked human and beatable in those fights.
I'm curious to see how he would do at 155.
