Discount NHL Jerseys . MORITZ, Switzerland -- Fog prevented downhill racers from getting their Olympic dress rehearsal. Rugby is returning to the Olympics for the first time in 92 years, bringing the ruck, the maul and the hooker back into the lexicon of the Summer Games.The format has changed, considerably, since the United States won the last rugby union Olympic gold medal in 1924, with the abbreviated seven-player version favored for Rio over the traditional 15-a-side game, and Fiji favored for a breakthrough triumph. The aim remains the same: score more tries -- grounding the ball in the opponents in-goal area -- and youre a good chance of winning.Its fast and physical, with more emphasis on speed and passing the ball (always backward) than heavy contact, and it is typically played in two seven-minute halves.Heres some things to watch in Rio, where the womens tournament runs Aug. 6-8 and the mens from Aug. 9-11 at the Deodoro Stadium:---FLYING FIJIANSFiji has never won an Olympic medal, but it has never had a chance to play its national sport at the Summer Games. The world series champions are favorites in the mens competition, and expectations are high in the Pacific.Englishman Ben Ryan took a squad containing an abundance of players with size, speed and natural flair for rugby sevens, and added extra discipline to every facet of the preparation from diet to drills. The result is a still entertaining, but more consistent Fiji team.Its the national sport, so our best athletes play rugby, Ryan says. We have been successful at it and thats also created this aura around the team, the way we play, totally different to every other side in the world. Its a risky, entertaining, exciting, slightly laid back -- sometimes -- way of playing the game. And we are doing it to a very high level.---GO BROSonny Bill Williams is a high-profile game hopper likely to feature for New Zealand in Rio, another notch in a career that has involved switching back and forth from rugby league to rugby union to win some of the biggest prizes in those sports.

He probably wont have to look far for family support, with his sister Niall figuring in selection calculations for the title-chasing New Zealaand womens team.dddddddddddd---POINT PROVEDThe sevens format has surged in popularity since its inclusion on the Olympic program, and the rewards are being spread more widely than ever. Countries such as Kenya and the United States have won titles on the world series circuit, and are ranked 6th and 7th behind southern hemisphere powers Fiji, South Africa, New Zealand, Australia and Argentina. American Madison Hughes led the world series with 331 points in the 2015-16 season. American speedster Perry Baker was second behind South Africas Seabelo Senatla for most tries scored and most line breaks.---WOMENS DRAWAustralia won the womens world series, reaching the final in four of the five tournaments to outpoint second place New Zealand, the dominant team in 2014-15.
