Dustin Poirier thinks Islam Makhachev's accolades make him undeniably the pound-for-pound No. 1 fighter in the world.Makhachev (28-1 MMA, 17-1 UFC), a former UFC lightweight champion and current welterweight champ, is tied with Anderson Silva for most consecutive victories in company history. He has an opportunity to break that record when he makes his first welterweight title defense against Ian Machado Garry (17-1 MMA, 10-1 UFC) in Saturday's UFC 330 (Paramount+) main event at Xfinity Mobile Arena inPhiladelphia."Anderson, his record was crazy, but what makes it more impressive is he's clearing out weight classes," Poirier said of Makhachev on Deep Waters. "He's beaten the best '45'er, cleaned out 155, went up, took the belt from the 170. That's what pound-for-pound really is."Makhachev holds the record for most UFC lightweight title defenses at four including a finish of Dustin Poirier at UFC 302. Poirier was able to defend 11 out of 16 takedowns but was ultimately submitted in Round 5. Poirier broke down what Machado Garry needs to do to find success against Makhachev."If he can keep Islam at the end of his punches and use good footwork, keep the fight in the middle of the octagon, stay off the fence, that's where he's going to have success, I think," Poirier said. "But, the first takedown, it's going to happen. He's not going to defend everything. His ability to get back up is going to tell the tale of the fight, I think."This article originally appeared on MMA Junkie: Dustin Poirier: Islam Makhachev defines 'what pound-for-pound really is'
