Sean McMahon has warned his detractors and positional rivals that he wont be giving up the Wallabies No.8 jersey without a fight.Coach Michael Cheika has endorsed the abrasive McMahon as the clear frontrunner to replace David Pocock, who will take a break from rugby in 2017, at the back of the Australian scrum.With Pocock out injured again, he gets another chance to prove his worth in Saturdays Rugby Championship clash against South Africa in Pretoria.The 22-year-old has heard all the talk before - that hes too short to play at No.6, too small to be an effective No.8, and unlikely to unseat Michael Hooper anytime soon at No.7.But that wont deter McMahon, who has vowed to make the position suit him, even if he doesnt traditionally suit the position.Any opportunity to throw on the gold is an opportunity and if eights going to be that opportunity, Im going to be taking it with both hands, McMahon said.Theres players like Lopeti Timani and that who could easily lock that role down or take it from me but I can tell you its not going to come easily - theyre going to have to work for it.Learning from a player like Pocock, who is also a seven whos worked his way into eight, I think hes proved that if youre capable (you can) go into that eight role and really make it your own.I might not be the tallest player out there, but Im going to (counter) that with speed.Ill just continue to bring that where I havent got the height.McMahon has had his tattooed left arm covered up during training this week after some recent new ink on his elbow - a third eye, which he admits doesnt hold any special meaning.Theres a few things on here that dont really mean much, were just filling her up at the moment, he said.But further up his arm, theres something that does hold significance - a quote he had etched as an 18-year-old that sums up his approach to rugby, and the reason why Cheika is such an unabashed fan of his.Life is what we make of it. If youre not willing to have a crack and have a dig, youre not going to get anywhere, McMahon said.Its probably what I take into rugby. If Im not going to be out there having a crack, whats the point in playing? Air Max 270 Sepia Stone .

Hey, hey, its time for everybodys favorite topic! You know what Im talking about ...Pound! For! Pound!Full disclosure: I remember sitting at a bar with another MMA reporter in Temecula, California, a few years ago and asking him something to the effect of, What is it with people and pound-for-pound lists? Everybody has got one. None are really right or wrong. Theyre basically pointless.The two of us then proceeded to argue about our pound-for-pound lists for at least 30 minutes, which is ultimately whats great about these lists. Even though I do still think they are rather pointless, they can be a lot of fun to argue about.So, lets have some fun.Lets take a look at my current pound-for-pound list and try to predict how it will change over the next 12 months. And keep an eye out for the female version coming soon.Who will still make the list?Demetrious JohnsonCurrent rank: No. 1And I think hell still be ranked No. 1. That would be quite something, since, according to the archives, I had DJ ranked No. 1 at this time last year as well. So, were talking about the UFC flyweight champion holding down the No. 1 spot two years running.I believe in the greatness of Jon Jones as much as the next guy, but Johnson has been more dominant (and active) in what Id argue is a deeper division. Hes the closet thing this sport has to a perfect fighter, and he has been for a while.Jon JonesCurrent rank: No. 2Its still strange to consider the very real possibility we havent seen him at his best yet. Jones has admitted that prior to his arrest on a hit-and-run charge in April 2015, he never reached his full potential due to issues outside the cage. In the 18 months since, he has fought just once (against Ovince Saint Preux in April) and looked rusty.Im willing to bet on Jones in the next 12 months -- but even with his talent, thats probably somewhat of a risky bet. This sport is hard enough without the self-sabotage.Dominick Cruz and TJ DillashawCurrent ranks: Nos. 3 and 4 respectivelyI think I have Dillashaw ranked higher than most. Im not sure about that since, as previously mentioned, I dont spend much time (i.e. none) looking at other pound-for-pound lists. Im very comfortable with that, though.Dillashaw is one of the most well-rounded fighters in the game, and I never thought his controversial decision loss to Raphael Assuncao in 2013 was legit. He really only has one definitive loss in his career and that was in his fifth pro fight. And considering A) How high I rank Cruz and B) How close their bantamweight title bout was in January (which Cruz won by split decision) ... how can I rank Dillashaw much lower?Who wont?Josee AldoCurrent rank: No.dddddddddddd6Sometimes MMA requires a great deal of reading between the lines. Theres plenty of misdirection when it comes to what fighters say, what promoters say and what coaches are willing to divulge. In a lot of ways, this sport is one big mind game -- and that refers to trash talk between fighters as well as negotiations between athlete and promoter.But with Aldo, at least right now, Im kind of taking his comments about not wanting to fight at face value. Do I actually believe hell never fight again? No, I dont. But do I believe theres a legitimate chance he has lost a little fire for cage fighting? I am willing to believe that. Whether due to inactivity or lack of motivation when he does step into a cage, I think Aldo could drop on this list.Stipe MiocicCurrent rank: No. 8Its the curse of being a heavyweight. It is really hard to stay on the pound-for-pound list as a heavyweight because youre always one split-second away from unconsciousness. I love Miocics mental approach and I dont really expect him to lose. Thats why hes on my list to begin with, but hes always at a higher risk of losing, simply because of the division he competes in.Who could really go either way?Conor McGregorCurrent rank: No. 5What is a pound-for-pound list? To me, its trying your best to envision every fighter competing in the same weight class. So, by default, if McGregor wins UFC titles in multiple weight classes, that would be a big reason to rank him extremely high.In other words, if McGregor, who holds the featherweight title, defeats lightweight champion?Eddie Alvarez next month and holds two UFC championships ... and then goes on to defend one of them a couple times next year, hell be in the conversation for best fighter in the world. At the same time, we still really havent seen him against a well-prepared wrestler. That wrestler question still exists. Does he have a hole there? It remains to be seen.What Im trying to say is McGregor shooting up this list or falling off it completely are both feasible options to me. So, I really have no idea where hell be come October 2017.Which new fighters will crack this list?Khabib NurmagomedovIve been riding this train for a while now, injuries and all. Might as well see it through.Luke RockholdFour months ago, you could have made a case Rockhold was Top 5 during his middleweight title reign. One Michael Bisping left hook at UFC 199 has silenced that. I think we were probably right back then and Rockhold just had a bad night. ' ' '
