Olympic hopeful Nick Dempsey is concerned his bid for gold at the Rio 2016 Olympic Games will be undone by a plastic bag floating in polluted waters.Britains sailors have spent a lot of time training in Guanabara Bay, trying to predict the climate patterns, tides and currents to aid their bid for glory next month.Yet Dempsey, who has been to Rio four times this year for two-week stretches, reckons the water quality is deteriorating and that someones medal chances in the RS:X mens windsurfer class in which he competes will be ended by debris in the water.Norwich-born Dempsey, who claimed silver at the London 2012 Olympics, said: Someone will lose a medal because of hitting something in the water.Its hitting the plastic bags in the water thats the problem. You stop, thats 10 places gone and youre not getting that back.Its going to happen -- its just how many times it happens to you. Its just going to be luck as to who gets the most plastic bags, hits a crate and that sort of stuff.Polluted waters can cause illness, too, and Dempsey, who returned from his most recent trip last Thursday, has not noticed an improvement despite the Games looming large.He added: Theres no improvements. Its worse. It was probably the worst its ever been last week. Its just rubbish in the water, everywhere. Its a bit of a nightmare. Theres nothing [the Rio 2016 organisers] can do about it. Its a huge, massive infrastructure problem.Dempseys training includes dealing with hitting debris, which is not difficult to incorporate when it happens so often.It happens every day in training, maybe three times that were racing that we have to stop, he added. Its become such a part of it that we do practice stopping, getting something off quickly and going again.You have to completely stop, reverse, go sideways and it generally comes off straight away. Its quite a slow process. Its going to happen at a crucial moment. Youve just got to get it off quickly.If it happens at the start line you will not finish top 15. Thats your race done.Windsurfers are affected more by the debris due to the light weight of their vessel, while dinghy sailors can be soaked due to their low position on the water.?The British sailors are doing anything possible to combat the threat of illness and expressed regret more has not been done to clean up the bay.Nick Thompson, world champion in the laser, said: When it rains a lot theres a lot of pollution in the water.Its a bit of a shame they havent taken the opportunity to clean the waters up a little bit more.Hannah Mills, London 2012 silver medalist in the 470 with Saskia Clark, said: Were a bit sad that hasnt happened.British Sailing team manager Stephen Park hopes a final clean-up will still take place and says that contingency measures are available so the level of debris does not affect the racing unduly.Some of that rubbish tends to lie in particular areas because of the way the water moves, Park said.If youve got to go across that line, as you approach that point youre looking closely in the water to see if you can avoid something.World Sailing are very conscious of that and if they think the rubbish is particularly bad, theyll probably move some racing to different courses. And, in theory, the Brazilians are going to do more to clean the courses.It is Brazil, they do have a habit of doing things very last minute. Well wait and see.?

Thats why Atlantic Coast Conference coaches are cautious about doing an all-access television show such as Showtimes A Season With.Many dont see the return on their investment as being worth it.I would at least want to hear them paint the picture of what it was really going to be like before I said yes or no, Virginia Tech coach Justin Fuente said.Many ACC coaches share Fuentes view -- they see the benefits, especially with recruiting, but wonder if those outweigh the potential distractions that could occur during four months of shooting.Florida State has opened its doors for this years series. The first episode aired on Sept. 6, which was the day after the Seminoles season-opening win over Ole Miss and airs on Tuesdays through Nov. 29.The series is similar to NFL Films Hard Knocks: Training Camp that airs on HBO during the preseason. North Carolina State coach Dave Doeren likes watching both to see how teams handle preseason practices. But when it comes to finding a strategic edge, especially with the Wolfpack hosting the Seminoles on Saturday, he didnt expect to find one.While the show may sway a couple future recruits, there are concerns about the potential distraction and impact it could have on a teams season.The Seminoles were considered to be a national championship contender before the season started but are 5-3 and ranked 19th. It is the first time since 2011 that they have entered November with three or more losses.Youd have to look at in totality and see what it did for you. Its certainly not helping them, Georgia Tech coach Paul Johnson said the programs impact on the Seminoles. Theyre 5-3. I dont know a team whos ever done it who had a good season.Stephen Espinoza, the executive vice president of Showtime Sports, said the production crew and school are in constant contact about storylines but that the network retains creative control. Schools see a copy of the show before it airs but that is to make sure no NCAA compliance violations are taking place and there arent any student-athlete privacy issues, especially with injuries.The reasons why the show is successful is it is someone from the outside giving a loook at a program.dddddddddddd It is something different than what would be produced by a conference or school, Espinoza said. The bottom line is that it is a relationship of trust. Were trusting the school to be open and candid and theyre trusting us to be objective.The show is likely to give Florida State another boost with a national audience getting a behind the scenes look Jimo Fishers program.Fisher said that high school players who have come in for visits have liked how it gives them a deeper look at the program.It is a different experience but it is like they (the production crew) are part of the football staff now, Florida State running back Dalvin Cook said. Its good that we get to show everyone what we do and the life of an athlete in college.Espinoza said that the network would like to get a geographic mix in future seasons but that he would not be averse to another ACC team doing it next year.Clemson would fit Espinozas formula: an elite program with a compelling coach, but linebacker Ben Boulware cant see the Tigers doing it, especially since they ban social media during the season.People would get to see the ins and outs of what we do, but for the players I think its a distraction, he said. Those lights and cameras are cool probably for about a week, but that definitely would get annoying.Another unlikely school is Virginia. First-year coach Bronco Mendenhall did a similar series last year when he was at Brigham Young and still regrets the decision.People act differently when cameras are around, and no matter how long theyre there, there still is an effect, he said. Highs are a little higher and lows are a little lower, and theres more drama and less work because its more story.After doing it -- and I was the one that wanted it and agreed to it -- the return on investment didnt give the outcome I was thinking it would.---AP Sports Writers Aaron Beard in Raleigh, North Carolina, Pete Iacobelli in Clemson, South Carolina, Hank Kurz Jr. in Charlottesville, Virginia, and Charles Odum in Atlanta contributed to this report.---The APs college football page: collegefootball.ap.org ' ' '
