Stage fright. Health. Confidence. These are just a few of the obstacles Tiger Woods faces this week in his anticipated return to competitive golf.So what else can we expect from the 14-time major winner? Our panel samples all things Tiger for this weeks edition of Monday Four-Ball.1. What will be the hardest obstacle for Tiger to overcome this week?SportsCenter anchor Jonathan Coachman: Confidence. From everything we are hearing, Tiger is physically ready to go. We arent talking about just another player. We are talking about the confidence to be a top-shelf player again. I am not talking about 2000 Tiger, but Tiger is special. Can he have the confidence in himself to be competitive and beat guys like Jordan Spieth or Jason Day? I dont care who you are -- confidence can help you overcome so much.ESPN.com senior golf writer Michael Collins: By teeing it up for four straight competitive rounds, hell be overcoming the hardest obstacle hes had to face -- time. Nothing is more difficult for a golfer than having to sit out and wait to get healthy. Besides that, trusting the new golf ball will be a big obstacle as well. Remember, it took Rory McIlroy a year to win after he switched golf ball companies.ESPN.com senior golf writer Bob Harig: His own expectations. Most realize that a 15-month break due to physical issues requires a grace period. Woods himself knows that. And yet, he admitted Sunday that his competitiveness makes it very difficult to not try to compete.ESPN.com senior golf writer Jason Sobel: Believe it or not, stage fright. As he told Bob Harig on the range Sunday, Tiger is going to feel some butterflies this week. Hell need to rise above it. Harvest the good energy and block out the bad. Its one thing to post a good score on his home course in complete privacy, or stripe drives on an empty range. Its another to do that with people watching all over the world.2. What do you make of Woods decision to change golf balls for the Hero World Challenge?Coachman: Tiger says it all starts with the ball. I am a little surprised he didnt go for Titleist, but leave it to Tiger to go against the grain. At some point he had to make the change, and why not do it out of the box in a small event in the Bahamas instead of waiting for a full-field event in the new year?Collins: Its a smart move to do it now so he can find out exactly how the ball will feel when he hits shots in tournament conditions. The hope is he will get in situations that he hasnt practiced for, so then hell learn exactly how the ball reacts on those ticklish shots that require the most nerve.Harig: It makes sense because Nike is no longer going to be making a golf ball. He needed to find something else, and its quite likely the Bridgestone ball he is using this week possesses very similar characteristics to what hes been using.Sobel: Good for him. Nikes decision to leave the equipment game opened the door for all of the players previously under contract to sample new things. If Tiger showed up this week with the same Nike ball and same equipment, it would show he either hasnt tested new stuff or doesnt care enough to switch. I like the fact that hes willing to explore whats out there.3. With so many questions surrounding Tiger, which one is the most important to answer this week?Coachman: For me, it would be Does his back pass the test? Once he gets through four rounds of walking and swinging, I honestly dont care where he finishes in the field. I just care that he finishes. He disappointed all of us when he didnt play at the Safeway Open in October, but if he comes out with a great attitude and in great physical condition, people will forget that very, very quickly.Collins: Most importantly for Tiger, how does he feel, health-wise, after every round? And then how does he feel after the tournament is over? Could he play again the following week? The health of his back, and health overall, will be the biggest question that needs answering this week.Harig: Can he play 72 holes without pain and discomfort? Getting through an entire week -- including practice, the pro-am and all of his other duties associated with the event -- should be considered a good first step in his comeback.Sobel: Can he legitimately walk 72 holes and post a decent score? I know that doesnt sound like much, but I saw where one betting parlor is taking nearly even money on Tiger retiring by the end of next year and has set the over/under on his number of starts at 6.5. People really seem to think hes done. That, if anything, is what he needs to disprove. This isnt about the result.4. Are you taking the over or the under of 72.5 for Tigers first-round score at the Hero World Challenge?Coachman: I am taking the under. I choose to believe in his greatness. I know one round doesnt determine that, but I think he is determined to come out of the box and show the world that he has his game right away. I believe he will shoot even par or better in his first round on Thursday.Collins: Over. Weve heard the, flushing it, crushing it, puring it on the range song way too many times before, followed by a 78. Tiger shooting par or better after 15 months off is a bit too much to ask even for a guy considered by many, including me, to be the GOAT.Harig: Over. Not because an under-par score is impossible. Who knows, perhaps Tiger shoots in the 60s. But this will be the first time in 15 months hell have a pencil and scorecard in his hand when it matters.Sobel: That sounds about right. Ill take a round of exactly 72.5. All right, considering theres no half-stroke at stake, Ill take the under. Why? Well, I do believe he wants to prove people wrong and will be amped up to compete again. But it has more to do with this: The early Thursday forecast calls for 81 degrees with a 40 percent chance of rain and only a 5-10 mph breeze. Thats called scoring conditions.Darrell Evans Jersey . -- Ryan Blaney provided more evidence that Penske Racings No. Dave Righetti Jersey . The Hall of Fame defenceman told Landsberg that he believes fighting still has a place in todays game, but thinks staged fighting needs be outlawed. https://www.cheapjerseysgiants.us/1066u-bobby-bonds-jersey-giants.html .

Anthony had 24 points and nine rebounds, and the Knicks avenged an embarrassing home loss with a rout of their own, beating the Boston Celtics 114-88 on Wednesday night for their third straight victory.Brisbane Roar coach John Aloisi is certain Jamie Maclaren will eventually become a permanent Socceroo despite an inauspicious showing on his competitive debut.Maclaren was thrown up front by coach Ange Postecoglou in Tuesday nights World Cup qualifier but like the rest of the team, was a long way from his best in a disappointing 2-2 draw with Thailand.The 23-year-old, whose only prior experience with the national team was in a friendly match against England earlier this year, might have been starved of service but he also failed to impose himself on the match and was taken off after just 57 minutes.But Aloisi reckons its way too early to cast judgement on Maclarens international future based on that display.Everyone was disappointed with the performance. None of the players played at their best, Aloisi said.We know hes going to score goals and eventually hell score goals for the Socceroos.Ange is smart enough and experienced enough to know not to blame any one individual.The media, I think, have to understand that Maccas going to be a Socceroo and hes going to score goals for the Socceroos.ddddddddddddBut we dont want to put that pressure on him yet because theres other experienced players in the Socceroos that could have played better the other night as well.Its expected Maclaren will return to Brisbanes starting line-up for Saturday nights A-League clash against Sydney FC, although Aloisi was non-committal on if hell play the full 90 minutes.Obviously it wasnt a great result for them over there, but hes come back, looked confident, hes scored a few goals in training this morning, Roar captain Matt McKay said.Its a great honour for him to go and get a game, and have that trust of Ange to start the game, a World Cup qualifier.That confidence, its hard to keep him down. Hell be right for us in the coming weeks.The Socceroos wont return to action until their next World Cup qualifier against Iraq in March next year, to be played on neutral territory in Tehran, Iran.
