NEW YORK -- It likely went down as the line of the night on Saturday at the UFCs historic debut at Madison Square Garden. But it might as well sum up Conor McGregors entire career.Id like to take a chance to apologize to ... absolutely nobody! McGregor said, setting off a cacophony of noise -- both supportive and derisive -- inside the legendary arena.McGregor, fresh off of making history at UFC 205 by becoming the promotions first fighter to hold world titles in two weight divisions simultaneously, need not seek repentance from anyone in the fight game. Not even as his behavior in recent days, from showing up late once again at Thursdays news conference to answering questions with constant profanity, has become increasingly crass for even his standards.The worlds most famous fighter took over The Worlds Most Famous Arena and made it his home on Saturday with a second-round knockout of lightweight champion Eddie Alvarez, just as he said he would do. In fact, just as he said he would do to every single fighter he has faced over 10 appearances in the Octagon since his 2013 debut -- save for a brief hiccup at welterweight against Nate Diaz in March, which he avenged four months later.As the great Muhammad Ali used to say, its not bragging if you can back it up. And until anyone at 145 -- where McGregor has held the UFCs featherweight title since last December -- or 155 pounds can do anything to stop him, the brazen Irish sensation has free reign to be just as Notorious as he wants to.The Ali reference is apropos in this sense because McGregor is the first combat sports athlete since The Greatest to truly possess Ali-like qualities. No, the parallel isnt perfect, particularly from the sense of cultural significance. But when it comes to entertainment value and the bold ability to back up the endless rhetoric that acts as his shield, McGregor stands alone within his own era.McGregors victory over Alvarez caps a 12-month span of financial and in-cage success that tops what any fighter has done in UFC history. So on the very same night as the 23rd anniversary of the UFC, in the promotions first appearance in the state of New York since 1997 following a well-documented battle, there was no other fighter worthy to have his face on the marquee on the brightest possible stage.Having already supplanted his contemporaries as the greatest draw in UFC history, McGregor is now attempting to creep closer toward the idea of becoming its greatest fighter, as well. No, hes not there yet. To many, he might not even be close. But hes building a resume that each day is becoming harder to quantify with an asterisk like what happens when he finally faces an elite wrestler with a full training camp? Those days, of penalizing his arrogance and lack of a complete game with qualifiers, is nearing completion.Are there fighters in both weight classes in which McGregor holds titles that you could legitimately favor to beat him tomorrow? No question. Unbeaten lightweight contender Khabib Nurmagomedov, who looked like a beast in mauling Michael Johnson on Saturday before calling out McGregor, is one of them.But the more he continues to make the kind of outrageous claims that hes talented and just crazy enough to actually back them up inside the cage -- while doing so in such spectacular and effortless fashion -- the closer McGregor comes to mixed martial arts immortality.Like Ali, he spoke of his all-time greatness from the very beginning, long before any of us -- or possibly himself -- was truly in a position to believe it. But theres no longer room to deny it.McGregor couldnt have said it any better Saturday after the fight when he proclaimed, Youve got to have size, reach, length -- youve got to have attributes to defeat me. One of those attributes is audacity, and right now he has no peer.For that, McGregor need not apologize. As long as he continues to back it up, the UFC is his world and the rest of us are just bystanders. Nike Zoom Canada .

Mercedes technical boss Paddy Lowe says Nico Rosbergs main area of improvement this year has been his racecraft.After being beaten to the title by Lewis Hamilton in 2014 and 2015, Rosberg only needs to finish second to his teammate at the four remaining races of the season to secure the drivers championship this year. While Hamilton has suffered more mechanical failures than Rosberg this year, the German has capitalised on his rivals misfortune by securing nine wins in 17 races.After observing Rosberg at the team for the last three years, Lowe believes the key to the Germans improvement this season has been the way he races against other drivers.I think Nico is an incredibly strong driver and I think we have seen over the last three years that he can qualify extremely well, he said. I think, for me, the step that he has made this year is that he has improved his racecraft considerably.Rosberg has incurred three high-profile penalties for his driving this year, one for colliding with Hamilton in Austria, one for running Max Verstappen off the road in Germany and one for barging past Kimi Raikkonen in Malayisa (pictured). But despite thhe stewards taking a dim view of Rosbergs driving this year, Lowe insists the overall change has been positive.ddddddddddddHes proving himself much better able to fight for the positions. Hes come across a few points along the way, with a few incidents that didnt quite come off how he wanted, but overall thats where he has made the step.Lowe says one of Rosbergs biggest problems is having to go up against a driver as good as Hamilton.Lewis gets better every year, Lowe said. He is a very, very difficult guy to beat for Nico, so in one way thats unfortunate for Nico to have such a strong teammate, but the two together are an incredible force for the team -- they push each other.Thats what is fantastic. When you have two very strong team-mates is that they actually elevate the total performance of the team, and we see that. We have races such as Monza where Lewis was incredibly strong and then Singapore where Nico was incredibly strong and thats what you need, for each driver to push each other to new limits. ' ' '
