One of the fun things about the weigh-in day at the World Team Trials is the watching which athletes have shown up to compete, and who decided not to enter. This is especially true during the year after an Olympic Games, when some athletes decide to retire and others decide to give it another try.    One of the American wrestling stars who are going for it once again is 1996 Olympic Greco-Roman silver medalist Brandon Paulson of Minnesota. Paulson made a run for a spot on the 2000 U.S. Olympic team, but fell just short, losing to Steven Mays in the gold-medal finals at the Olympic Team Trials in Dallas.     When Paulson did not enter the 2001 U.S. Nationals, many believed that his career may have been over. However, the fire to compete still burns within Paulson, who won his Olympic medal while still a young man, still just, a student at the Univ. of Minnesota. Now, five years later, married, with children, and working full-time, wrestling takes a different role in Paulson's life.    "Training has gone pretty good," said Paulson, right after making 119 pounds at the weigh-in, and clearly lean and mean and ready to wrestle. "It's a little harder with a job, two kids and a wife. I figured a way to do it all, and get the training time in."    Dan Chandler, Paulson's coach with the Minnesota Storm, understands the challenge facing Paulson and is confident that he still can be a world-class star.    "He now has two kids and all the territory that goes with that," said Chandler. "He's trying to support his family. He didn't feel that he would be ready for the U.S. Nationals. He is ready now."    Paulson, who works as the vice-president for sales for JR Wrestling Products, believes his new approach to the sport might help him in this tournament.    "I'm confident that I can do well in this tournament," said Paulson. "I didn't do two years straight of training like I did for the last Olympic Games. It might be better for me. The pressure is off now. I'm not really worrying about it. The whole world doesn't depend on it. This is something I am doing to have some fun. I still think I can compete."    Chandler believes that his loss in the 2000 Olympic Trials still burns in his heart and will be a motivating factor for him. Steven Mays, the man who beat him, also has entered the tournament after sitting out the U.S. Nationals. Also in the Challenge Tournament at the weight class is Shawn Sheldon, a 1988 and 1992 Olympian, meaning all three of the past Olympians from the United States are in the tournament bracket.    "He didn't like the way he went out in Dallas and decided to give it another attempt," said Chandler.    Paulson, like many of the other entries, is coming back for a shot at the World Championships in New York City, Sept. 26-30. He wants to be able to wrestle in front of family and friends at that level at least one more time.    "I want to get to the World Championships and wrestle in front of the home crowd," said Paulson. "I remember the Olympic Games in Atlanta; the home crowd was excited. I hope we have an even bigger and more excited crowd in New York."    Paulson is not the only 1996 Olympian from Minnesota who is back in action after sitting out all of the 2001 season. David Zuniga, who was 10th in the Atlanta Olympic Games, but fell short in the 2000 Trials, is also back for another try. "I figured, what the hell, one more time," said Zuniga.    The inclusion of some familiar faces from the past makes the Challenge Tournament in all three styles very exciting this year.
