José Aldo is one of the greatest mixed martial artists of all time. Furthermore, he remains the greatest featherweight in MMA history. In the aftermath of his stunning 13-second knockout loss against Conor McGregor, Aldo was the recipient of an avalanche of disrespect from a majority of the casual fans that the Irishman brought into the sport.Many dismissed Aldo's accomplishments in the sport, while others leapt onto a different bandwagon once McGregor abandoned the division in pursuit of UFC lightweight gold.Once Max Holloway captured the promotion's featherweight championship from José Aldo and mounted 2 title defenses, UFC color commentator Joe Rogan was quick to discount the Brazilian's legacy by proclaiming Holloway the featherweight GOAT.However, José Aldo is not merely the greatest featherweight in history, he is also an MMA GOAT regardless of weight classes. Having recently retired from MMA, 'Scarface' leaves behind a massive legacy that everyone will struggle to match.In honor of his historic run in the UFC, this list details the 5 reasons why José Aldo is an MMA GOAT.#5. José Aldo is the greatest anti-wrestler in MMA historyAs a Brazilian, José Aldo has no formal background in wrestling. Yet, the Brazilian somehow built the greatest defensive wrestling system in MMA history.José Aldo's MMA debut came in 2004, almost two decades ago. Typically, somebody who has been an active fighter for that long meets opponents who have tailored their fighting style and gameplan to beat them. However, Aldo's takedown defense remained impregnable across 39 fights in an 18-year career.During his reign as the featherweight champion in the WEC and the UFC, José Aldo encountered a string of elite wrestlers and even a judoka. Urijah Faber, Chad Mendes, Frankie Edgar and Ricardo Lamas all failed to outwrestle the Brazilian. Manny Gamburyan was unable to use his judo against José Aldo.Even years afterward, with a mountain of fight tape on Aldo's defensive wrestling, Merab Dvalishvili failed on all 16 of his takedown attempts against 'Scarface'.Gonzalo Campos MMA@campos_gon Jose Aldo is the first fighter that Dvalishvili couldn't takedown in the UFC (10 bouts).

He widened his base and threw his hips back while snapping his upper-body weight onto the back of his opponent's neck.However, he rarely needed it. Instead, when opponents shot in for takedowns, José Aldo immediately hooked his arm over one of his foe's arms.If the takedown was a double-leg, the Brazilian turned it into a single-leg by overhooking his opponent's arm and turning sideways to feed his hip to his foe. At that point, Aldo freed his arm before shoving his opponent's head down to his ankle and hopping out of their grasp.If the takedown was a single-leg, half of his work was already done for him. He retired with a takedown defense rate of 91%.
