OMAHA, Neb. -- The U.S. Olympic swim team has a history of improving its times from the trials to the games.The Americans are counting on it happening again next month in Rio after not setting a single world record during the eight-day selection meet.Led by Michael Phelps and Katie Ledecky, the U.S. still boasts the most powerful swim team in the world.But other countries have improved since four years ago in London and Phelps knows hes got to be much better by the time the Rio Games begin.Clearly, theres cause for concern.Many of the times swum in Omaha were slower than the 2012 trials, where no world records were set. Ryan Lochte and Missy Franklin struggled this time around and theyll be joined by 29 rookies on the team, one more than in London.Were going to have to improve for sure, David Marsh, head coach of the U.S. womens team, said Sunday.Phelps has said he wants to swim another personal best at least once before he retires after Rio. He was faster at last years summer nationals where he swam times that would have won medals at the world championships in Russia.Its been 2009 since Ive done a best time, he said. Its frustrating to not be able to go the same time or faster than I did last year, especially because I think Im in better shape than I was last year.Phelps joked that if Bowman doesnt have a plan to make him faster hell have to fire the only coach hes had his entire career.His times this week were mediocre, and Im crystal clear on what to do, said Bowman, who will guide the U.S. men in Rio.Phelps qualified in three individual events, Ledecky and newcomer Maya DiRado made it in three each, and Franklin will swim two.Ledecky carries huge expectations into her second Olympics. In January, she lowered her own world mark in the 800-meter freestyle at a meet in Austin, Texas, where she set world-leading times in the 200 and 400 freestyles. Shell try to become the first woman since American Debbie Meyers at the 1968 Mexico City Games to sweep the 200, 400 and 800 free.Im just going to focus on my racing and what my goals are, and anybody elses expectations dont really mean that much to me, Ledecky said.The average age of the mens team is 23.9 years, with Anthony Ervin the oldest at 35. The womens team averages 22.3 years, with Ledecky the youngest at 19 just as she was in 2012.Several stalwarts of the U.S. team failed to punch tickets to Rio, including Natalie Coughlin, Tyler Clary, Matt Grevers, Cullen Jones and Jessica Hardy. All of them medaled in London, where the team won a leading 31 medals, including 18 golds.Its challenging being at trials and being able to make the transition from here to the games, Phelps said. You got to be ready when the lights come on and if youre not, you could fall short by a hundredth or a few hundredths, and thats the tough part.Heading to his fifth and last Olympics at 31, Phelps appears more willing than he has in the past to share his experience and expertise with his younger teammates. He certainly has more time, with eight events no longer on his schedule.If I can do anything to help the rookies, Im all for it, he said. Just being able to help them just kind of stay in their relaxed zone, not get worked up because it is the Olympics. Its just another meet, you know? Wade Boggs Jersey . After Mondays hard-fought loss, the wait seemed longer than usual. Getting set to go their separate ways for a short Christmas break, the Raptors coach credited his team for their effort on a seemingly impossible three-game road trip, urging them to build on that success when they get back to work at the end of the week.

Cheap Red Sox Jerseys . -- Chicago Bears cornerback Tim Jennings was selected Monday to his second straight Pro Bowl, while guard Kyle Long made it after a solid rookie season. LINCOLN, Neb. -- Knocked unconscious in last weeks game, Nebraska quarterback Tommy Armstrong Jr. wasnt medically cleared to play against Minnesota until hours before the Saturday night.Everything was going great until the third quarter when he injured his left ankle on a sneak and needed help to the sideline. When the offense returned to the field early in the fourth, Memorial Stadium roared at the sight of Armstrong, and he went on to lead the No. 19 Cornhuskers 91 yards to the tiebreaking touchdown in a 24-17 victory.Armstrong scored the winner himself, tweaked his hamstring as he crossed the goal line and was carried to the bench by offensive linemen Tanner Farmer and Jerald Foster like a conquering hero.Tommy is the toughest dude Ive been around, said safety Kieron Williams, who finished off the Gophers with an interception with 1:29 left. A lot of quarterbacks wouldnt have played a snap. People can say what they want about him. I wouldnt want to go to war with any other quarterback.The Huskers (8-2, 5-2 Big Ten) still need to win out and have Wisconsin lose once in order to reach the conference championship game. But the night was a perfect re-set for a team that had lost two straight, including that humiliating 62-3 beat-down at Ohio State last week.Armstrong, who spent the week going through the concussion protocol, played one of his best games in weeks and outperformed Minnesotas Mitch Leidner. Armstrong was 19 for 27 for 217 yards with two touchdowns, and he ran nine times for 61 yards. His last run was a 13-yarder to break a 17-17 tie with 7:17 left.Before starting the winning drive, offensive coordinator Danny Langsdorf and coach Mike Riley asked Armstrong if there were certain types of plays he didnt want called because of his health.I had to suck it up and know I would be OK, Armstrong said. I told them to open up the playbook. If we needed quarterback runs, I was there to runn.dddddddddddd If we needed to throw outside the pocket, I could do that, too.Riley said Armstrongs competitiveness showed through against the Gophers (7-3, 4-3).He doesnt ever like to come out of the game. He always thinks hes going to make the next play, Riley said.Nebraska allowed a season-low 265 total yards, with Aaron Williams and Josh Banderas making 11 tackles apiece.The Huskers trailed at halftime for a fourth straight game. Newby tied it 17-all in the third quarter, taking a screen pass from Armstrong 31 yards to the end zone.You go the road and you have a chance, said Gophers coach Tracy Claeys, whose team had its four-game winning streak end. But we didnt play well enough in the second half to win the ball game; Nebraska played better than we did.THE TAKEAWAYMinnesota: The Gophers lost control of their destiny in the Big Ten West. They might regret some of their play-calling against the Huskers. Other than a few occasions Rodney Smith bounced to the outside for good runs, it was mostly futile for them to try to run up the middle.Nebraska: If anyone doubted Armstrongs toughness, he proved his mettle. He also showed he is the most important player on this team. If he goes down, the Huskers are in deep trouble.POLL IMPLICATIONSWith Virginia Tech and North Carolina losing, Nebraska could move up a spot or two.SHUTDOWN DEFENSEMinnesota out-yarded the Huskers 172-137 in the first half but managed only 93 yards and no points the rest of the way.We were a little out of whack and not playing our ball, Banderas said. Older guys took charge and knew what we had to do.UP NEXTMinnesota hosts Northwestern, which shut out the Gophers 27-0 last year.Nebraska hosts Maryland in the first meeting of the teams.---More AP college football at http://collegefootball.ap.org Cheap Nike NFL Jerseys Cheap Jerseys China Stitched Jerseys China Jerseys Cheap Jerseys Store Youth NFL Jerseys Cheap Wholesale Nike NFL Jerseys Discount NFL Jerseys Wholesale NFL Camo Jerseys Wholesale NFL White Jerseys Wholesale NFL Camo Jerseys White NFL Jerseys Cheap Camo China NFL Jerseys Cheap NFL Jerseys Jerseys NFL China ' ' '
