Note: An athlete must win the pool competition in order to advance into the championship bracket and remain eligible for a medal.     55 kg/121 lbs.    There is no doubt that some World champions will be eliminated in the pool competition at this division. There are two pools in this weight class with a pair of past World champions  in the same draw.     Pool 2 features 1999 World champion Lazaro Rivas of Cuba and 2001 World champion Hassan Rangraz of Iran, which some people believe may be the two best athletes in the field. The other person in the pool will be wildcard Samir Benchanaf of Algeria.    Pool 6 features 2002 World champion Guidar Mamadaliev of Russia and 2003 World champion Dariusz Jablonski of Poland. The third athlete in this rough draw is Mukresh Khatri of India.    There is some good balance in all of the other pools, although a few of the might be a little easier than the others.    Dennis Hall of the USA, a 1995 World champion, has two solid opponents. Petr Svehla of Czech Republic was fourth in the 2003 World meet and Oleksiy Vakulenko of Ukraine placed 10th in the World meet.    Pool 1 features talented Masutoshi Toyoda of Japan and Istvan Majoros of Hungary, plus wildcard Jansel Ramirez of the Dominican Republic.    Pool 3 has 1997 World champion Ercan Yildiz of Turkey, and veteran Irakli Chochua of Georgia, plus Svajunas Adomaintis of Lithuania.    Pool 5 has the 2003 World silver medalist Im Dae-Wong of Korea, plus veteran Marian Sandu of Romania, who was fifth at the 2003 World Championships. Nurbakhyt Tengizbayev of Kazakhstan is also in this draw.    The last group, Pool 8, has four athletes, with the winner advancing directly to the semifinals. Uran Kalilov of Kyrgyzstan, who was sixth in the World last year, and Haakan Nyblom of Denmark, are top challengers in this group. Also in this pool is European silver medalist Artiom Kiourgegkian of Greece and Jiang Sheng of China.    Basically, the pools will weed out talented wrestlers, including some World champions, setting up some difficult quarterfinals. This weight class has been hard to predict and this draw will help continue that tradition.    66 kg/145.5 lbs.    This weight class has some killer pools, with two pools featuring a pair of past World Champions. Of the six pools, all but one should feature strong competitors in a very competitive setting.    Pool 1 has a pair of World champions in 2002 World champion Jimmy Samuelsson of Sweden and 2001 World champion Vaghinak Galustyan of Armenia. Making this even more difficult is the third man in the draw, Maxim Semenov of Russia who was fourth in the 2003 World meet.     Pool 5 has four competitors, and two of them were past World champs, with 2003 World champion Manuchar Kvirkelia of Georgia and 1997 World champion Seref Eroglu of Turkey. Also in this stacked pool is 2003 World silver medalist Armen Vardanyan of Ukraine. The fourth athlete is not in this caliber of wrestler, Luis Izquierdo of Columbia. This will be a true battle.    Pool 3 is loaded, with a 1996 Olympic champion in Ryszard Wolny of Poland, a 2000 Olympic silver medalist in Juan Maren of Cuba and a 2003 World silver medalist in Farid Mansurov of Azerbaijan.    Pool 2 is difficult, led by 2000 Olympic silver medalist and two-time World champion Kim In Sub of Korea. Levente Furendy of Hungary, a 2003 World bronze medalist, is in this pool, as is Nikolay Gergov of Bulgaria.    Pool 6 has four athletes, including American Oscar Wood. The athlete with the most achievements is two-time World champion Mkkhitar Manukyan of Kazakhstan. Also in this pairing is Jannis Zamanduridis of Germany and Konstantinos Arkoudeas of Greece. Wood has a chance to make a name for himself if he makes his way past these competitors.    The weakest pool is Pool 4, with Kanatbek Begaliev of Kyrgyzstan, Parviz Zeidvand of Iran and Moises Sanchez of Spain in this pairing. Whoever emerges will have a tough quarterfinal, with the winner of the Wolny/Maren/Mansurov battle waiting for them.    This stacks up with enough talent that by the time this division reaches the semifinals, the athletes there will have had to beat some tremendous competitors.    84 kg/185 lbs.    This weight class has a pretty good spread of talent across the six pools. No pool is way overloaded, and no pool is without somebody with strong achievements.    The toughest pool may be Pool 4, with 2003 World champion Gotsha Tsitsiashvili of Israel and 2001 World silver medalist Alexei Michine of Russia in the draw. The unlucky third person in this pool is Melonin Noumonvi of France.    American Brad Vering, fifth at the last two World meets, has a loaded draw in Pool 2. He faces 2001 World champion Mukhran Vaktangadze of Georgia and 2002 World bronze medalist Mohamed Abd El Fattah of Egypt. If Vering survives this pool, he is well on his way to big success at the Olympics.    Pool 5 has four wrestlers, led by two-time Olympic champion and three-time World champion Hamza Yerlikaya of Turkey. His top challenger may be 2001 World bronze medalist Oleksandr Daragan of Ukraine. Also in this pairing are Vladislav Metodiev of Bulgaria and Tarvi Thomberg of Estonia.    Pool 6 also has four athletes, led by 2002 World champion Ara Abrahamian of Sweden, who was also second in the 2003 World meet. Looking to knock off Abrahamian will be Attila Batky of Slovakia, Janarbek Kenjeev of Kyrgyzstan and Shingo Matsumoto of Japan.    Perhaps the top wrestler in Pool 3 is Fritz Aanes of Norway, who was fourth in the 2003 World meet. This pool features two wrestlers who have served two-year suspensions for doping violations, Aanes and Behrouz Jamshidi of Iran. Aanes tested positive at the 2000 Olympics and Jamshidi at the 1999 World meet. Also in this draw is Dimitrios Avramis of Greece.    Pool 1 is led by Levon Geghamyan of Armenia, who was fourth in the 2002 World meet. His pool rivals will be Viacheslav Makaranka of Belarus and Andrea Minguzzi of Italy.    120 kg/264.5 lbs.     This weight class has only two past World champions in the draw, and a limited number of past World or Olympic medalists. The talent is spread out pretty well, although there is one pool which has considerably less talent than the other five.    2000 Olympic champion and 2001 World champion Rulon Gardner of the United States drew into Pool 6, which has four competitors. His top challenger could be Sergeuy Mourieko of Bulgaria, a four-time World-level medalist who boasts a 1996 Olympic bronze medal. The others in this grouping are Minduagus Mizgaitis of Lithuania (fourth in 2004 Worlds) and Marek Mikulski of Poland.    The other gold medalist in the field is 2003 World champion Khassan Baroev of Russia, who is in Pool 3 with David Vala of Czech Republic and Andrei Chekhouskoi of Belarus. Baroev will be favored to emerge from this grouping.    An interesting pairing comes in Pool 4, with Yuri Yevseychyk of Israel, who was fourth in the 2000 Olympics, and Pan American champion Mijail Lopez of Cuba. Lopez has won a few matches over Gardner, but has not placed higher than sixth at a World meet. Also in this grouping is Yilmaz Gul of Turkey.    Pool 2 features four-time World silver medalist Mihaly Deak-Bardos of Hungary, who has veteran Juha Ahokas of Finland and up-and-coming Sajad Barzi of Iran in his pool.    Pool 5 has four athletes, led by a pair of past World bronze medallists, Georgiy Tsurtsumia of Kazakhstan and Xenofon Kousioumpas of Greece. Also in this grouping are veteran Eddy Bengtsson of Sweden and Mirian Giorgadze of Georgia.    The weak pool is Pool 1, with Yannick Sczcepaniak of France (8th in 2003 Worlds) and Haykaz Galastyan of Armenia (9th in 2003 Worlds), plus Rafael Barreno of Venezuela.    Rulon Gardner is looking to become the first U.S. Greco-Roman wrestler to win two Olympic gold medals. If he wins his pool, he moves directly into the semifinals, a good position to be in. The top half of the draw has the most stars in it, while Gardner is in bottom of the draw.
