One year ago, the picture at 66 kg/145.5 lbs. in Greco-Roman seemed fairly clear heading into the U.S. Nationals. 2000 Olympian Kevin Bracken of the New York AC had dominated U.S. competition for a number of years, and possibly the only wrestler who could stand in his way would be Faruk Sahin, a Turkish wrestler who gained U.S. citizenship shortly before the Nationals.    But Bracken was defeated in the quarterfinals by Oscar Wood of the U.S. Army, who had not won a national title of any kind since 1995, when he competed in the Junior Nationals. Wood was then dropped by Sahin in the finals, before Sahin failed a drug test for which he was suspended for two years from competition.    Wood not only received the bye in the Olympic Trials, but he then proved himself again by defeating Bracken twice in a best-of-three series for the Olympic spot. Bracken has since retired, and after a short break from competition, Wood is back in the mix, ranked No. 1 for the first time in his career heading into the U.S. Nationals. Only this time, he won't surprise anyone at what may be the deepest weight class in Greco-Roman in the U.S.    Marcel Cooper and Glenn Garrison of the U.S. Army are both ranked high. These are two veterans who have been on the National Team before, and their experience should be valuable in a one-day tournament. Wood defeated Cooper earlier this year, and Garrison's only U.S. loss is to Harry Lester of the Sunkist Kids.    Lester, also a resident at the U.S. Olympic Education Center at Northern Michigan Univ., has continued to succeed at higher levels each of the last three years. This year, many believe he is good enough to jump to the next level and possibly earn a spot on the U.S. World Team. He recently won the Dave Schultz Memorial International after defeating some high-caliber competition.    Ranked low on the ladder right now, but expected to have a major impact at this weight, is Brandon McNab of the U.S. Army. McNab joined the Army following the Olympic Trials and due to boot camp, has not yet competed this year. But last year, he finished strong at the U.S. Nationals and placed fifth at the Olympic Trials. He may start this tournament off a little rusty, but he will definitely be a bad draw for somebody.    Mike Ellsworth of the New York AC is another veteran in this weight class. He seems to finally be getting 100% healthy, which could be dangerous for his competition. Ellsworth placed second to Lester at the Schultz tournament in an exciting finals match. For the past four years, Ellsworth has been a force in overseas competitions, and now he will be set to prove himself as a force in the U.S. again.    Another Olympic Training Center resident who has continued to improve is Mark Rial of the Gator WC, who placed seventh at the Olympic Team Trials last year. Rial has had some big wins this year, but he has lost twice to Lester and once to Cooper in a tight match.    Heath Sims of the Dave Schultz WC was an Olympian in 2000, and will always be regarded as a dangerous foe in these competitions. Under the new rules, anybody is a contender now, especially in Greco-Roman. The new rules could have been a career revival for Sims.    A few young wrestlers to watch out for will be Jacob Curby of the USOEC and the Gator WC, Mervin Ford of the Gator WC and Cam Jones of the New York AC. These are three wrestlers who have continued to gain experience and could pull off an upset at any time.    2004 U.S. NATIONALS RESULTS  1st - Oscar Wood, Fountain, Colo.
