When the World Cup of Hockey kicks off on Sept. 17, the best players from around the globe will vie for international hockey supremacy.A deep dive into the eight rosters assembled for this tournament offers a glimpse into where the worlds best hockey players come from -- not simply which country develops top hockey talent, but which individual programs form the most prolific NHL pipeline.ESPN.com examined each World Cup roster, including players who will miss the tournament because of injury, to find which programs are the top NHL incubators. Here is the list of the worlds top hockey factories.London KnightsIt makes sense that this list would start with the Memorial Cup champions. In total, 33 Ontario Hockey League alumni were selected to compete in the World Cup, outpacing any other developmental league. Every World Cup team will ice at least one former OHL player. Among Canadian junior teams, the Knights and Kitchener Rangers of the OHL and the Portland Winterhawks of the Western Hockey League lead the competition with five players each. London sticks out by virtue of the names it has developed, including Patrick Kane, John Tavares and John Carlson, although Tavares played only 38 total games for the Knights.Kitchener is one of the big programs, along with London. They do a great job of recruiting players, going into the depths of the small towns to find good talent, said Ric Jackman, a former NHLer who has played professionally in eight different countries and whose former OHL team, the Sault Ste. Marie Greyhounds, boasts four alums in the World Cup. The product [the Knights] put on the ice and the amenities they have -- with that great arena and the success that theyve had over the years -- I can understand why players from the United States or Europe want to go play there.United States National Team Development ProgramIf the OHL has historically been the main channel for NHL talent, the USNTDP is the new model. Team USAs 23-man roster includes eight players developed in the program. And its reputation continued to grow after nine USNTDP players were taken in the first round of the 2016 draft, including three of the top seven picks. Team North America, which features the best players age 23 and under, has eight USNTDP grads of its own, including top talents Jack Eichel, Dylan Larkin and 2016 top pick Auston Matthews.University of MichiganWith five Wolverines headed to the World Cup, Michigan distinguished itself among Division I teams, edging out Minnesota and Wisconsin, which each boast four alums in the tournament. Michigan, which has won nine NCAA championships, has built quite a program under longtime coach Red Berenson. However, Minnesota -- which will have four former players who represent three different countries in the World Cup -- has shifted the recruiting model by attracting both local and international talent.I dont think we were winning the recruiting battles. We were losing kids to Wisconsin. Thats when [Minnesota] opened it up to other kids, said former NHL player Craig Johnson, a Minnesota alum who now coaches at Santa Margarita Catholic High School in Southern California. It proved successful. They ended up winning a couple of national championships after they did it.Perhaps most surprising is the scant representation from East Coast powerhouses Boston University (Eichel) and Boston College (Johnny Gaudreau, Cory Schneider), which combine for three players in the tournament.FrolundaOne of the favorites to take the tournament, Swedens World Cup team draws talent from a variety of historic programs. But Frolunda leads the team with five players, including key pieces Henrik Lundqvist, Erik Karlsson and Loui Eriksson. The club -- which is captained by Lundqvists twin brother, Joel -- won the Swedish Hockey League title last season.Djurgardens and Modo are right behind Frolunda, with four players each. But while Djurgardens is located in Stockholm and draws from a larger talent pool, Modo is among the worlds legendary programs. Located in the town of Ornskoldsvik (with a population less than 29,000), the club has groomed legends Peter Forsberg and Markus Naslund. The Swedish team is led by three prominent Modo alums in Daniel Sedin, Henrik Sedin and Victor Hedman.KladnoThe club known for developing Jaromir Jagr, who is now its part-owner, has six former players on the Czech roster. Located northeast of Prague, Kladno is among Europes oldest clubs and has overseen the development of top Czech forwards David Krejci, Tomas Plekanec and Jakub Voracek. But Canadian junior leagues have proven just as responsible for grooming top Czech prospects. Of the 23 players on the Czech roster, 15 played Canadian junior hockey. The Quebec Major Junior Hockey League has become the go-to destination for Czechs looking to refine their game: Eight members of the World Cup team have played in the league.Karpat and JokeritWhile Czech players typically leave their country early, Finns prefer to stay home until they get their call from the NHL. When it comes to the programs furnishing the Finnish team, two clubs reign supreme. Karpat and Jokerit boast six and five World Cup players, respectively, and have a history of producing top talent.They play a real team game. Theyve kind of molded their systems around the North American NHL style, said Jackman. You could see how a lot of players would learn their trade on their pro teams over there. There is a direct transition for them to step into the NHL and be successful.Karpats alums on the national team include key players Pekka Rinne, Mikael Granlund and top prospect Sebastian Aho. But Jokerit will always be known as the club that gave the world Teemu Selanne and Jari Kurri, the two greatest players in Finnish hockey history. Those two names -- and Jokerits Helsinki location -- have helped developed an elite program whose top team moved to the Kontinental Hockey League in 2014.Honorable mentionsDukla?Trencin: Slovakia has fallen behind in its overall hockey development, but this club -- located in the modest western city of Trencin -- has four former players in the tournament, including Slovakian legends Zdeno Chara, Marian Hossa and Marian Gaborik.Lokomotiv Yaroslavl: No one club dominates Russias national team. Yaroslavl and Sibir Novosibirsk both feature three players on the roster. But Yaroslavl is a considerably smaller city that has contributed key Russian players Semyon Varlamov, Dmitry Kulikov and Artem Anisimov. Air Max 720 Australia Wholesale .C. - The Carolina Hurricanes have placed backup goalie Anton Khudobin on injured reserve with an unspecified lower-body injury. Air Max 720 Wholesale Australia . The move comes after the Canadiens were approached by the Buffalo Sabres for permission to speak to Dudley - a former Sabres player and head coach. "The Sabres called for permission and I appreciate that, Im flattered, Dudley told TSN Hockey Insider Pierre LeBrun of ESPN. http://www.airmax720australia.com/ . This should be celebrated because it will not always be this way. With the amount of money given to players by their clubs these days, it is a wonder that so many of those teams allow the sport to continue to take away many of their assets so they can play for a different team in the middle of their season.

MINNEAPOLIS -- Heres a look at Sundays preseason games around the NFL. (All times EDT):THE SHIP COMES INSan Diego at Minnesota, 1 p.m.The Vikings will take the field in their gleaming new stadium for the first time, showing off the $1.1 billion venue to their fans -- and the Chargers, whose 15-year quest to replace aged Qualcomm Stadium has yielded only uncertainty about the franchises future in San Diego. An attempt to move to Los Angeles last winter was blocked by the Rams and the NFL.The Vikings were once a candidate to move, but theyre not going anywhere now with light-filled, ship-shaped U.S. Bank Stadium now towering over the east edge of downtown Minneapolis where the Metrodome once stood. After a public open house, an international soccer exhibition and a couple of concerts, from country singer Luke Bryan to hard-rocking Metallica, its finally time for football under the translucent roof.Hopefully we can make this a home, Vikings coach Mike Zimmer said.Running back Adrian Peterson will just be a spectator against the Chargers.The 10th-year veteran, who has not taken a preseason snap since 2011, was given the choice of whether or not to play a few downs but opted not to.I just really thought about it and didnt feel like it was the best thing, Peterson said.An awkward season for the Chargers has started as poorly as possible with the holdout of defensive end Joey Bosa, the third pick in the draft whose representatives have clashed with the front office over seemingly minor structures to his contract.HONEY BADGER IS BACKArizona at Houston, 4:25 p.m.Cardinals all-Pro safety Tyrann Mathieu, who came off the physically unable to perform list last week after finishing his recovery from a torn ACL in his right knee that kept him out of the playoffs last winter, will make his preseason debut with 10 to 12 plays against the Texans. So will cornerback Justin Bethel, who had foot surgery in the spring and is competing with Mike Jenkins and rookie Brandon Williams for the starting cornerback spot opposite Patrick Peterson.The Cardinals, after advancing further into the NFLs elite with a 13-3 regular-season finish in 2015, will undoubtedly be looking around at Houstons NRG Stadium and pondering the possibility of a February return for the Super Bowl.The Texans will have a valuable opportunity to test their passing game against one of the leagues best defenses, with new quarterbaack Brock Osweiler aiming to build off a solid performance last week against New Orleans when he led the first team to 13 points in the first half.ddddddddddddRookie wide receiver Will Fuller, a key addition to the offense, was the target on the touchdown pass against the Saints and finished with 73 yards on four catches.LOOKING AT LAFELLCincinnati at Jacksonville, 8 p.m.One of the biggest issues for the Bengals this season will be the replacement of wide receivers Marvin Jones and Mohamed Sanu, their top two targets behind star A.J. Green who left as free agents. Second-round draft pick Tyler Boyd has impressed the team in limited action in the first two exhibition games, including a 40-yard catch in the opener and a diving 26-yard grab to go with a 12-yard touchdown reception last week.Brandon LaFell is the other newcomer, having left New England to join the Bengals, but an injured right hand that kept him out of the first two games has kept his impact on the offense more of a mystery. The seventh-year veteran is expected to play for the first time at Jacksonville, an important step toward building chemistry with quarterback Andy Dalton.Theyve practiced together for three and a half weeks, but the game is a little different because you can get tackled, coach Marvin Lewis said. Thats the biggest difference. Its a positive for him to get an opportunity to play.The Jaguars will be closely watching left tackle Kelvin Beachum, playing his first game since tearing the ACL in his left knee last October.After signing a five-year, $45 million contract with Jacksonville, the former Pittsburgh Steelers starter sat out the teams entire offseason program and the first two exhibition games while completing his recovery from reconstructive surgery. The Jaguars have slid over Luke Joeckel, the second overall pick in the 2013 draft, to left guard in attempt to solidify an offensive line that allowed an NFL-high 122 sacks the last two years.Jacksonvilles first-team offense will be out to replicate sharp performances in the first two preseason games. In five possessions, the Jaguars starters have produced three touchdowns and a field goal for 24 points.---Online:AP NFL website: http://www.pro32.ap.org and AP NFL coverage on Twitter: http://www.twitter.com/AP-NFL ' ' '
