Focus on ... Mercedes reliabilityWith both its drivers still in the running for the title, Mercedes is becoming increasingly concerned about reliability. The problems that affected Lewis Hamilton earlier in the season cannot be undone, but with three grands prix remaining the team is determined that a car failure does not decide the drivers title in the final races. Of all the remaining races, Mexico is arguably the most difficult from a reliability perspective, with the thinner air at 2,250 metres creating a number of potential reliability and set-up issues.From a technical point of view, the key feature of this race is the high altitude at which Mexico City is situated - giving it an atmospheric pressure of less than 80% of normal levels, Mercedes technical boss Paddy Lowe explains. This brings with it a reduction of aerodynamic forces, both downforce and drag, while the turbocharged Hybrid Power Unit is still able to deliver its normal level of power.The knock-on effect is that this circuit is tough on tyres, as grip levels are very low, and tough on brakes thanks to high speeds combined with low levels of cooling and drag. So, there are a lot of things to manage through the weekend simply to keep both cars healthy.At the same time, its tricky for the drivers, as they are essentially running downforce levels equivalent to Monza at a circuit with significantly more twists and turns. That creates some headaches for them behind the wheel but also the potential for some great racing.Although the turbocharged V6 engines are able to produce the same amount of power at the higher altitude, the turbo has to spin faster than usual to achieve that output and cooling can become marginal.One area you have to pay particular attention to on the power unit side is the cooling as the less dense air is not only less effective for combustion, its also not as strong on the cooling side too, Renault technical director Bob Bell explains. You maintain the same level of power, so you have to dissipate all the energy. With less effective air going through the ducts there was certainly a question mark last year. If its a particularly high ambient temperature we will need to monitor the situation closely as well likely be at a very high operating temperature.In short, everything should be fine, but there is a chance that teams can push the cars too far in the pursuit of performance. No pressure, then.In need of a podiumA podium is all Nico Rosberg needs to keep his title campaign on track. He can afford two second place finishes and one third place at the remaining three races and still come out on top in Abu Dhabi. He claims he is going for wins at each round, but no one would blame him if he started taking fewer risks and settled for second place this weekend.In need of pointsRomain Grosjean proved the Haas is still capable of picking up points this year and that should be all the incentive Esteban Gutierrez needs to score his first points of the season. His future at Haas is still up in the air, but a solid finish in the points would make the decision that bit easier for team bosses Guenther Steiner and Gene Haas. If he gets those points in front of his home crowd in Mexico, it will be all the more special.ESPN predictionLewis Hamilton looked like a new man in Austin as he notched up win No. 50 of his career and put an end to a five-race victory drought. He needs to do the same again this weekend to keep his title chances alive and just one week on from the U.S. Grand Prix he should be able to keep that momentum going.WeatherDry weather is expected for Friday, Saturday and Sunday. This is normal for this time of year in Mexico City, as the end of October is the beginning of the dry season that continues all the way through the winter months. However, some showers cannot be ruled out during the afternoon and evening hours. But its not going to be warm out there, with highs expected to be between 16C and 19C.A lap with ... Romain GrosjeanLong straight line going into turn one with big braking, 90 degrees right-hand side, followed by a small chicane. Its very important to get the second part right because youve got another long straight line. Then youve got another 90-degree left corner, and then a 90-degree right corner. Thats followed by a very weird double right-hander. Its very difficult to find a line. Then you go to the middle section which is flowing, with mid- to high-speed left and right corners. Next its the entry to the stadium - big braking here, very tricky with the wall facing you. Then its a very slow hairpin in the stadium, as slow as Monaco. Finally, its the double right-hand corner with very important traction going into the old part of the oval to finish the lap.TyresCompounds: Medium, Soft, Super-softAlong with Monza and Baku, Mexico is one of the fastest circuits on the 2016 calendar. However, the cars run more downforce than at Monza, partly to compensate for the altitude.The asphalt is still new, as the circuit was resurfaced for last years inaugural race (smoothing out the bumps that used to be typical of Mexico). The surface may have evolved this year.Mexicos most famous corner -- Peraltada -- is the one that takes most energy from the tyres.Weather is always a question mark, with both warm conditions and heavy rain possible.Last year, the track was slippery: however the circuit has been quite extensively used by a number of different championships during the season, which should lay more rubber down.

Most important, perhaps, it went off without a hitch. Organizers poked a little fun at the now-infamous opening ceremony gaffe that saw only four out of five snowflakes open up into rings, leaving the Olympics logo one ring short. http://www.hydroflaskwaterbottleuk.com/ombre-hydro-flask-24-oz-standard-mouth-flamingo-water-bottle.html . - After leading the Saints to a fourth playoff appearance in five seasons, Drew Brees expressed confidence in the direction of his team and, perhaps more importantly, showed a willingness to listen to contract proposals if the team needs his help getting under the NFLs salary cap. Ombre Hydro Flask 21 oz Standard Mouth Mint Water Bottle . The Americans, skipped by John Shuster, seized the advantage in the eighth end by scoring five points for a 7-3 lead. The Czechs pulled two back in the ninth, but Shusters team of third Jeff Isaacson, second Jared Zezel and lead John Landsteiner ended with another point to secure the last Olympic berth on offer. Ombre Hydro Flask 40 oz Wide Mouth Lemon Water Bottle . Once again, DeLaet finished tied for second at a PGA Tour stop on the weekend, this time at the Waste Management Phoenix Open. The pride of Weyburn, Sask. ATLANTA -- Dustin Johnson launched a drive on the practice range at East Lake and some 320 yards away, saw it take one hop off the green meshing on the fence. Not satisfied, he teed up another and let it fly, this one clearing the fence.This is what makes Johnson so appealing. But its not what makes him so good.Look back to Riviera Country Club on a rainy Wednesday in February, when Johnson finished his pro-am round and headed out to the range to try using a computer model for the first time -- but only for his wedges. He got those dialed in this summer, and he suddenly looks hard to beat.Thats why Johnson is a U.S. Open champion and the No. 1 seed going into the Tour Championship, making him the favorite to win the FedEx Cup and its $10 million bonus.Hes kind of figured out the way hes supposed to play golf now, Brandt Snedeker. You look at him, and he checks all the boxes of what a No. 1 player in the world looks like. Its been fun to watch him evolve into that player.Johnson is coming off a victory in the BMW Championship, his third of the year.But with the points being reset at the Tour Championship, anyone has a mathematical chance of claiming the FedEx Cup, and the top five players only have to win to take home the biggest payoff in golf.THE TOP FIVE: Aside from winning, the goal in three FedEx Cup playoff events leading to Atlanta is to get into the top five. Those are the one who have a clear shot at the $10 million prize.Johnson won the BMW Championship. He is followed by Barclays winner Patrick Reed, Adam Scott, world No. 1 Jason Day and Paul Casey. Missing from that group is Rory McIlroy, who won the Deutsche Bank Championship but wound up as the No. 6 seed.Casey went to No. 5 on the strength of successive runner-up finishes, while Scott went to No. 3 by finishing fourth in all three playoff events.THE HISTORY: This is the 10th year of the FedEx Cup, and if history is any indication, most of the field can stop dreaming about ways to spend $10 million.The No. 1 seed going into the Tour Championship won the first three years -- Tiger Woods twice and Vijay Singh. The No. 2 seed has won the last three years -- Jordan Spieth, Billy Horschel annd Henrik Stenson.ddddddddddddOnly twice has the FedEx Cup champion come from outside the top 10 -- Jim Furyk was No. 11 in 2010, while Bill Haas was at No. 25 in 2011.THE COURSE: The PGA Tour decided to switch the nines at East Lake to make for a more compelling finish. So instead of that long, uphill par-3 closing hole, the finish now is a par 5 in which tee shots have to be in the fairway to have any chance at reaching the green. Theres a pond, but its about 80 yards from the green and mostly comes into play when someone tries to clear it from the rough.It should make for a little more excitement, possibly even an eagle.PGA Tour Commissioner Tim Finchem said last year that if it comes down to the wire and attracts more TV viewers, it will take longer to play a par 5 than a par 3, and the audience might stick around longer. Thats one case of simple math in the FedEx Cup.THE PICK: Still to be determined is the final American to be picked for the Ryder Cup, and the Tour Championship could go a long way in sorting that out.U.S. captain Davis Love III invited Bubba Watson, Daniel Berger and Justin Thomas to Hazeltine over the weekend to play the course, and its clear hes looking at all three of them to return next week when it counts.THE OTHER BATTLE: Dustin Johnson and Jason Day are the leading candidates to be PGA Tour player of the year, which is a vote of the players after the Tour Championship. Day figures he will have to win at East Lake to have any chance, and if he does, he thinks that will be enough to win the vote.That would give him The Players Championship, the Tour Championship, the Arnold Palmer Invitational and the Dell Match Play, along with being the FedEx Cup champion. It might be enough to win the money title, provided Johnson finishes worse than third.Johnson, meanwhile, is in good shape to win the Vardon Trophy for lowest adjusted scoring average, and his three victories are the U.S. Open, the Bridgestone Invitational and BMW Championship. Advantage, Johnson.At least until the Tour Championship is over. cheap falcons jerseys cheap ravens jerseys cheap bills jerseys cheap bears jerseys cheap bengals jerseys cheap cowboys jerseys cheap lions jerseys cheap texans jerseys cheap colts jerseys cheap jaguars jerseys cheap chiefs jerseys cheap rams jerseys cheap dolphins jerseys cheap vikings jerseys cheap saints jerseys cheap giants jerseys cheap jets jerseys cheap eagles jerseys cheap steelers jerseys cheap 49ers jerseys ' ' '
