CHARLOTTE, N.C. -- Only five games into the season and the Carolina Panthers look nothing like the team that went 15-1 last year and lost in the Super Bowl.These days, the reigning NFC and three-time NFC South champions are struggling with a little of everything -- shaky defense, injuries, turnovers, you name it -- in a shocking 1-4 start to the season.And after a mistake-filled 17-14 home loss to the Tampa Bay Buccaneers on a last-second field goal, the Panthers are left to explain how they can turn it all around.Stuff like this happens in the NFL, cornerback Teddy Williams said. You can be great one year and come back and have a season like this. But at the end of the day were only five games in, you really can circle the wagons and know that its a long season, and come back strong and really finish stronger than you started.Injuries have been a huge problem, starting with Mondays absence of reigning NFL MVP Cam Newton. He missed this one after suffering a concussion after taking a hard shot to the head when he pulled up near the goal line on a 2-point conversion in a loss at Atlanta.Carolina has also been without top tailback Jonathan Stewart since Week 2 with a hamstring injury. Two other starters, left tackle Michael Oher (concussion) and cornerback James Bradberry (toe), were also out along with first-round draft pick Vernon Butler (ankle) at defensive tackle.But the problems run deeper, starting with the fact the Panthers are committing way too many mistakes.Carolina had four turnovers Monday night, three coming from backup quarterback Derek Anderson. The most costly was a goal-line interception in which Anderson threw into double coverage looking for Greg Olsen -- Brent Grimes made a leaping grab in the end zone -- with the teams tied at 14-all midway through the fourth quarter.That pushed the Panthers to 14 turnovers through five games after committing 19 during their 15-win regular season a year ago.Carolina got the ball only once more, a three-and-out that ultimately led to the Buccaneers winning drive. By the end, Carolina had finished with nearly 100 more total yards (414-315) but plenty of empty possessions.We moved the ball when we wanted to, Anderson said. We did a lot of good things. Unfortunately we had bad plays at the wrong time. Thats kind of what it came down to.Overall, Carolinas offense is averaging about a touchdown less per game from its NFL-best 31.2-point average last season, while the defense has struggled to get a pass rush and is surrendering 27 points per game after allowing about 19 a year ago.Carolina is also committing more penalties. Theyve committed 39 penalties for 330 yards, including a 15-yard facemask by Kony Ealy while trying to tackle Jacquizz Rodgers in the final minute to set up Roberto Aguayos 38-yard field goal for the win.The Panthers travel to New Orleans this weekend before getting a needed bye. They can only hope that gives them a chance to get healthy and regroup.The things that we arent doing a good job of, we need to fix, center Ryan Kalil said, and we need to fix them right away.---Follow Aaron Beard on Twitter at http://www.twitter.com/aaronbeardap and the APs NFL site at http://pro32.ap.orgCheap San Francisco 49ers Jerseys .

Larry Collmus has stepped down as the wintertime racetrack announcer at Gulfstream Park. No replacement has been named.Collmus, 49, who began calling the races at Gulfstream in January 2007, cited the desire to lessen his workload, which includes calling races at the New York Racing Association tracks -- Aqueduct, Belmont, and Saratoga -- seven months of the year as well as being the voice of the Triple Crown and Breeders Cup. Collmus informed Gulfstream Park management of his decision Wednesday morning.I will not be returning as the announcer for the winter meet at Gulfstream, Collmus said. Its been a good 10 years, but I feel at this time of my career that its in my best interests to cut back my schedule. Ill be 50 years old in October, and the wear and tear of nearly year-round race-calling will catch up to my body and brain eventually.A winter break will boost my energy levels and give me an opportunity to keep the creative juices flowing. I am extremely fortunate to work for the NYRA and for NBC Sports, and I think I owe it to them to be the best I can be for many years to come.Pete Aiello calls the races at Gulfstream from early April through November. Though Gulfstream officials said Wednesday that no decision has been made on Collmuss replacement, it is expected thaat Aiello will be offered the wintertime position.dddddddddddd Last winter, Aiello called the races at Oaklawn Park, which means that track could need an announcer for the 2017 meet.In a statement, Gulfstream Park president and general manager P.J. Campo said: We totally understand where Larry is coming from. Hes under tremendous stress each day with everything hes doing, and Larry is a perfectionist. We appreciate everything Larry has done for Gulfstream. Hes been a true professional and a great friend to Gulfstream. We wish him all the best moving forward.Collmus, who has called races at a plethora of tracks starting in 1985, said he worked at Gulfstream on a year-to-year oral contract. In the summer of 2014, Collmus signed a five-year contract to call the races at NYRA, taking over for the retiring Tom Durkin.In April 2015, Collmus began his NYRA duties. He calls the races at Aqueduct, Belmont, and Saratoga from April through October.Asked if he planned to pick up any more work from NYRA, Collmus said, At this point, nothing changes with my NYRA schedule.From November to March, John Imbriale and Travis Stone split the race-calling job at NYRA.
