Sky Sports have delved beyond the gorilla tattoos and catchphrases to ask whether Conor McGregor is really worth it. I am not retired McGregors statement in full The brash Irishman feigned retirement and was officially removed from his UFC 200 rematch against Nate Diaz before boldly declaring I am not retired to return to the pinnacle of his sport.Is it all an act? We spoke to people who know McGregor best. The previous victims Conor McGregor (left) knocked out Dustin Poirier in Las Vegas Dustin Poirier was seen as the opponent who could stop McGregors hype in the Irishmans Vegas debut. Poirier lasted less than two minutes.Poirier said: Conor is definitely the real deal. Ive had 22 fights and Ive never been put out like that. I was very emotional, just because of everything that had gone on between me and Conor. The build-up to the fight between us made me fight emotionally, rather than relaxed, which is how I like to fight.He hit me with a good shot and I went down. Id love to do it again. I wouldnt get hit with that shot again, and I wouldnt let myself get so emotional. McGregor knocked me out! Dustin Poirier shares memories of his darkest day Dave Hill lost to McGregor four years ago on the regional circuit. He remembers a cocky Irish kid with remarkable self-assurance.Hill said: I thought it was all an act, all for show. He was kicking off at the weigh-ins. But when he got in my face, because of his intensity, I thought: He really believes in himself. That flustered me.Hes overwhelming in a fight because hes always in your face, hes so confident. He was talking to me during the fight, saying I look soft, and it made my mind go elsewhere. I was thinking should I say something? He has a presence that doesnt give you a rest and puts you on the back-foot.I dont think its an act any more. But when I started fighting him I realised that he believes everything he says - thats the way he is.The coaches I knew Conor would be a great fighter but I didn’t know he would become so popular. He was always a charismatic guy but I couldn’t have predicted how big he would get. He never has moments where that gets on top of him. Pressure is for tyres. Head coach John Kavanagh Phil Sutcliffe was the first man to teach a 12-year-old McGregor to punch at Crumlin Boxing Club, but doesnt remember an outstanding talent.Sutcliffe said: He was like any other novice who we taught the basics to. Hes ambidextrous, we teach that to all our kids, he can box orthodox or southpaw. His straight left changes fights. Its an opportunists punch - hes always had the ability to turn on his back leg to throw his back hand. If he didnt have the right attitude, he would have never made it to the top. I remember the first day meeting him. I remember the confidence Conor had. He was immediately the best boxer we had. You could take him down and submit him but he was never fazed. He knew he could knock you out Striking coach Owen Roddy The fellow UFC champion UFC middleweight champion Luke Rockhold said he is intrigued by Conor McGregor’s rise The team-mates Aisling Daly, McGregor, Paddy Holohan & Cathal Pendred are SBG gym products Aisling Daly, a UFC womens straw-weight contender, has risen through the ranks alongside McGregor at Dublins SBG gym.Daly said: Hes still the same guy that I knew when we were teenagers but he has fancier shoes and nicer cars. Everything else about him is the same. He makes everyone realise that, with hard work, they can have the mansions and the fancy cars too.Because were a family theres no begrudging him, were all sending positive vibes to him. When one of us makes it, we all make it. Were all in the gutter looking up at the stars. Sometimes Conor will turn up for training in a five-piece suit but, on a normal day, hes rolled out of bed and arrived in a beanie hat and a tracksuit. Hes like the rest of us. Conor is a phenomenal striker and I’ve been learning from him for years. He’s definitely one of the best strikers in the UFC. Gunnar Nelson The promoter McGregor was spotted by the UFC after a successful stint with Cage Warriors Graham Boylan runs Cage Warriors, a domestic promotion that gave McGregor his big break.Boylan said: Without doubt, hes our biggest export, nobody can deny his prestige. I remember the phone call when I offered him a title shot and he said Ill fight tomorrow.When we had Conor for his fifth and sixth fights, we knew hed go on to special things. He just acted differently to everybody. He stood out from a crowd of 30-odd fighters, everybody was looking at him. People with long teeth behind the scenes realised that if he could back up the things he was saying then hed be a star. Conor won all his fights in Cage Warriors because he got into his opponents heads.The future foes We know that Conor has lost twice by submission. He was willing to give up twice, we know that. He tapped out to a choke and a knee hold, which is a move where you give up before it becomes a problem because you’re anticipating pain. I’ve seen that he is capable of giving up. Urijah Faber Frankie Edgar, ranked No 2 at featherweight, isnt impressed by McGregors talk.Edgar said: Maybe he is the second coming like hes been telling everyone! I dont get caught up in the attention around McGregor. Is he skilful? Yes. Does he bring attention to the rest of us? Yes. But hes not always respectful.Donald Cerrone also resides in the lightweight and welterweight divisions, but respected McGregors KO of Jose Aldo.Cerrone said: Unbelievable, man. The dude went out there and did everything that he said hed do. He shocked the world in 13 seconds. How awesome is that?The boxer Hes a character with no regard for anyone or anything which you admire as a fighter. I know people who have boxed with him in Ireland - hes from a boxing background. Hes certainly a better boxer than the others. George Groves The sports scientistProfessor Greg Whyte puts McGregor through a series of tests to compare him against other sportsmen.Whyte said: His VO2 max is similar to a Premier League midfielder. They run 10-12km a game with short breaks whereas Conor competes for up to 25 minutes. That is all-out effort and his endurance capacity is right up there with the best midfielders. It is his ability to recover before returning to his peak which is impressive and those values are similar to those of footballers. McGregor the compete package Read about his remarkable fitness His power output on a bike is not like an Olympic cyclist but what separates Conor is that he can do it all. He outperforms a cyclist in other areas. Also See: I am not retired Why did he retire? Who is UFCs real No1?

RIO DE JANEIRO -- Like many of the golfers who came to Brazil to participate in the Olympic golf Tournament, Justin Rose has taken time to soak in the experience.Typically its all business at golf tournaments, but Rose has found that enjoying the atmosphere and meeting others from the Great Britain Olympic scene has been a benefit.Its what everyone is here for, said Rose, whose 69 on Friday during the second round left him tied for fourth, 4 shots off the lead held by Australias Marcus Fraser.In the wider Team GB, its what everyone trains for, Rose said. Its what they expect. I think its the kind of event that obviously theres three places that are worth shooting for, and then theres kind of you are there to compete as an Olympian.At the end of the day, theres a pretty finite goal this week. Its either achieve or you dont. Saying that, youre going to come out of this week with a memory that will last a lifetime. If you dont come away with a medal, I think youre still going to look back fondly on the experience.Obviously as a competitorr, youre gunning for the top.ddddddddddddRose has given himself that chance this weekend at the Olympic Golf Course after rounds of 67 and 69. Ranked 12th in the world, hes gone through a bit of a slow stretch following a back injury that kept him out between the Players Championship and the U.S. Open.Since returning, Rose has not cracked the top 10 in any event, playing just the three major championships and the WGC-Bridgestone Invitational.Yet he has gradually returned to form and sees no reason why he cant make a run, despite not being at his best for the first; two days.They certainly dont give anything out today, so all you can do is put yourself behind with an uphill struggle, but I feel like I havent done that, Rose said. I feel like Im in a good position going into the weekend. I feel like I have another gear or two to try and find, and it would be nice if it all clicked into shape when you need it. ' ' '
