Aldo's old, his legs are shot and so is his gas tank. It's why Stephens did so well, in pockets Aldo could outclass him but he couldn't match the output, cut an angle or get Stephens out of his face for the majority of the night. What we saw tonight is that Aldo would get seriously hurt if he fought a real boxer, these guys still think they're 25 and that they can learn, grow and improve and they don't believe in their own flaws and age. Being a fighter is a double edged sword, you have an insane about of self belief but you are also often incredibly delusional and that shit gets you hurt at the end of your career.
