Novak Djokovic stood stoically, as still as a stone -- was it another strong take on the mannequin challenge? -- and the smoke billowing at Londons O2 Arena began to engulf him.Before his opening match at the Barclays ATP World Tour Finals against Dominic Thiem?on Sunday,?Djokovic stood there and briefly closed his eyes, and you have to wonder whether, even for a moment, he wished he could make himself disappear.For four of the past five seasons, Djokovic has finished as the No. 1-ranked player. He could still make it five out of six with a victory in this eight-man event, something that, based strictly on history, wouldnt be terribly surprising; he has won each of the past four editions of this tournament.After losing the No. 1 last week to Andy Murray, the world No. 2 essentially needs to go one step further than Murray in London.With Djokovics uneven 6-7 (10), 6-0, 6-2 victory over the 23-year-old Thiem, it would be a little too easy to declare Djokovics glorious run of dominance over. But its not irresponsible to wonder whether his shelf life at the top has a rapidly advancing expiration date.The recent signs, including this manic match with Thiem, arent particularly good. Lets just say that for Djokovic, the end of the season cant come fast enough.The frustrations were still evident Sunday, even after a smooth final two sets. In his postmatch news conference, Djokovic had a heated exchange with reporters when the world No. 2 found himself on the defensive answering questions about his recent bouts of temper. Heres how it went down:Question: Back to the end of the first set, we saw you similarly venting your frustration at Roland Garros, throwing your racket. Does it concern you one day that will cost you dearly? If it hit someone ...Djokovic: You guys are unbelievable.Q: Why is it unbelievable?Djokovic: Because youre always picking these kind of things.Q. If you keep doing these things ...Djokovic: I keep doing these things? Why dont you get suspended then?Q. You were close, werent you?Djokovic: Im close? Im still not suspended, so if Im not close, Im not close.Q: If that ball had hit a spectator, it could have been serious.Djokovic: It could have been, yes. It could have snowed in O2 arena, as well, but it didnt.Q: Youre not concerned about your mindset?Djokovic: Im the only player that shows his frustration on the court? Thats what you are saying?Q: Youre one of the top-ranked players in the world.Djokovic: So?Just five months ago, Djokovic seemed invincible. He won the Australian Open, the rare Indian Wells-Miami double and then the French Open, completing his career Grand Slam. That was his 12th major singles title, and that noise you heard was the crunching of all-time numbers.How long before the 29-year-old Serb caught his long-time rivals, Roger Federer (17) and Rafael Nadal (14)? Since taking three Grand Slams in 2011, Djokovic had won an astounding 11 of 22 majors up to that point. That trajectory would vault him past Nadal -- and Pete Sampras, too -- by the end of 2017. Federer would be in his sights by 2018.And then Djokovic -- perhaps in retrospect it was inevitable -- came back to the field. He lost to Sam Querrey in the third round at Wimbledon, Juan Martin del Potro in his first match at the Rio Olympics and Stan Wawrinka in the US Open final.After falling to Marin Cilic in the quarterfinals of the BNP Paribas Masters earlier this month, Djokovic unblinkingly tackled the elephant in the room: his disturbing and dramatic loss of confidence on the court.A lot of things, a lot of emotions went through my mind and body in the last two years, Djokovic said, with the things that I was blessed to achieve, obviously, and the career Grand Slam this year. But it took a lot out of me, and it has put some things in perspective and, obviously, raised some questions in which direction I want to go to.So Im in the process at the moment, and its going [to] obviously take some time really for me to redefine all these things.Against Thiem, it took a 69-minute first set to accomplish that reset.Djokovic was tentative in that frame and Thiem was consistently fiery. Then, after earning three set points in the tiebreaker, Thiem succumbed to nerves, pounding back-to-back double faults and a tight backhand into the net. Finally, on his seventh set point, he whipped a forehand winner.At one point, Djokovic lost his racket and his legendary balance, winding up on his behind, then offered a thin smile -- maybe it was actually an embarrassed grimace.Whatever it was, it returned him swiftly to full power.As Federer and Nadal have both learned, the 30th year of a professional tennis players life can be a difficult one. After winning his 16th major, at the 2010 Australian Open at the age of 28, Federer has won only one since. Nadal had just turned 28 when he won the 2014 French Open -- and he hasnt won one since. Sampras, too, won one major after turning 29.Djokovic celebrated his 29th birthday just before the French Open. He has struggled with physical and mental issues ever since winning that cherished, life-changing title.This season-ending tournament offers a revealing glimpse into his psyche.Look, in the end of the day, I have to get to that state of mind where Im able to perform as well as I want to match after match, Djokovic said at the Paris Masters. I was not able to find that level for last couple of months.But Im still here, and I feel like Im on the right path. Im in a better state of mind than I was some time ago. Thats all Im thinking about right now. Cheap Adidas Superstar Online .

LINCOLN, Neb. -- Nebraska coach Mike Riley is impressed with the resiliency his team has shown under difficult circumstances the past month.The Cornhuskers have had to adjust to the absence of popular assistant coach Keith Williams, who was arrested on suspicion of third-offense drunken driving last weekend. His arrest came two weeks after the funeral of punter Sam Foltz, who died in a car crash in Wisconsin along with former Michigan State punter Mike Sadler.Riley said after practice Wednesday that he has been worried about his players ability to maintain a focus on football after all thats happened.There have to be things on their mind almost continually, he said. The thing Im impressed with is how they perform. They put a smile on their face. For anyone going to work, the attitude you bring and how you present yourself and how you like doing what youre doing means a lot to me about how its going to go. So for whatever reason, however theyve done it with all the stuff thats gone on with these young men, I think theyve done really well that way.Williams has not been at practice since he was arrested early Sunday after he rear-ended a Uber drivers vehicle in downtown Lincoln. His blood-alcohol level was reported at 0.15, nearly twice the legal limit of 0.08. That high a reading could have led to a felony charge for aggravated DUI. He instead was charged with misdemeanor DUI and cited for careless driving after the non-injury crash. He pleaded not guilty.Riley had no update on Williams status with the program.This is a most, most, most serious situation, he told reporters. We are still exploring and talking and finding out as much as we can. This is ongoing right now in-house and because of the seriousness of it, I just dont have anything else to really givee you, OK? When I do, it will be definitive and that will be it.ddddddddddddGraduate assistant Hardie Buck, a receiver and special teams player on Alabamas 2009 and 2011 national championship teams, is coaching the receivers in Williams place.Weve been OK.

Weve come out with a great attitude and have had a positive attitude through the whole thing.Receiver is among the Huskers deepest positions, with Westerkamp and fellow seniors Brandon Reilly and Alonzo Moore taking on additional leadership and helping young players get lined up and understand the offense.Its tough, Westerkamp said, because its your position coach, specifically for the wideouts. Hes a guy out there every single day with you.
