After years of coming close, T.C. Dantzler of the New York AC took over this weight division last year with an explosive burst of offense. Dantzler avenged his many losses to veteran Keith Sieracki of the U.S. Army in the World Team Trials finals. At the World Championships, Dantzler put on a throwing clinic with wins in his pool, but was eliminated from medal contention in the championship bracket. He showed how exciting he can be with another throwing party in a victory during the Titan Games. Now that he has finally reached No. 1, it may be very hard to take the top spot away from Dantzler.    Sieracki beat Dantzler in the U.S. Nationals finals last year, 4-1, only to lose the best of three series in the World Team Trials. A 2001 World Team member, Sieracki had Dantzler's number for many years. He will be motivated to reclaim the edge this year. Sieracki is still motivated to make the Olympic team, after the controversy from the 2000 Trials concerning Matt Lindland, as well as his runner-up finish at the 1996 Trials. Sieracki can pummel with anyone, and also has the ability to throw when he is wrestling wel..    Coming in at No. 3 is another young talent, Darryl Christian of the Dave Schultz WC, who also has tremendous athletic skills and competitive fire. Like Dantzler, he has learned his trade at the U.S. Olympic Training Center. Christian was fourth in a very competitive division at this year's Dave Schultz Memorial International. Christian comes off a disappointing sixth place at the Pan American Championships.     Jake Clark, the most accomplished of the exciting Clark brothers in the Marines, holds the No. 4 Team USA ranking. He has competed at 85 kg often, so there is no certainty that Clark will be in the mix at this division in Las Vegas. 2000 Olympian Heath Sims of the Dave Schultz WC is a veteran who is always a threat to win in any tournament. Sims has been competing on the international level since high school, and is in his fourth Olympic four-year cycle as one of America's top talents.    Keith Barkers of the U.S. Marines has been in the mix during recent seasons, and seems to compete well at the major competitions. Tom Ciezki of the Wildcat WC was fourth in the U.S. Nationals last year, but may be moving up to 185 pounds this season. If he moves up to this division, Steve Woods of the U.S. Air Force will be a threat, having placed sixth at the Granma Cup in Cuba at this weight. Brandon McNab of the New York AC has also been a career Greco-Roman specialist, and has shown in recent events that he will be a factor at this division.    Brian Van Hoven of the U.S. Marines, Josh Henson of the Dave Schultz WC, veteran Jeff Funicello of the Sunkist Kids and Ken Cook of the Cyclone WC are other athletes who are expected to challenge at the U.S. Nationals this year. Cook won this year's University Nationals, scoring a technical fall in the finals and beating his opponents by a 55-1 margin.    2002 U.S. Greco-Roman Nationals results at 74 kg/163 lbs.  1st - Keith Sieracki, Fort Carson, Colo. (U.S. Army) dec. T.C. Dantzler, Colorado Springs, Colo. (New York AC), 4-1  3rd - Darryl Christian, Colorado Springs, Colo. (Dave Schultz WC) dec. Thomas Ciezki, Evergreen Park, Ill.
