Aldo has 9 title defenses. 7 in the UFC, 2 in the WEC, which was already the #1 promotion for below 155 at the time. Just look at his victories. Mike Brown ( when he was nearly at his best ) Urijah Faber ( leg kick destruction ) Chad Mendes x2 Cub Swanson Frankie Edgar Ricardo Lamas KZ Gamburyan ( the only man to KO him at 145. ) Kenflo He has beat pretty much everyone at 145 that is elite, I dont think Conor can beat him. Just look at the resumes and fights and who they have fought, but I will say Conor may the last interesting fight for Aldo at 145. Other then rematches, he needs to move up and fight elite 155ers.
