A few blend in with the rest, hiding among the throngs of expanding waistlines and facial hair. A few stick out like sore thumbs, fresh out of high school and look like they could be competing.    They hold the un-enviable position of officiating the Cadet and Junior National tournament but they're relatively new at it.    The contingent of officials the past few years in Fargo has seen an increasing number of men and women in their late teens and early 20's stepping up and filling the shoes of the most seasoned freestyle and Greco referees.    T.J. Brablec of Winter Haven, Fla. is officiating his fifth tournament in Fargo, days after his 23rd birthday.    Bout 298, a cadet 135-pound match between Maryland's Alex Ward and Nebraska's Aaron Denson, is underway, and Brablec is on the mat.    He raises his right hand to indicate two points, but pulls it back towards his ear to let the mat chairman confirm. It's a style that gave all the other officials a little laugh.    "What? Are you shooting them," the mat chairman asks, joking at Brablec's hand motion.    That's the kind of week it is for officials in Fargo, young or old, a job to be done and a job to have fun… and it starts early if you want to officiate in the world's largest wrestling tournament.    "I started when I was 16. As an athlete, it was a good deal. My entry fee was paid for tournaments if I would work the rest of the tournament," Brablec said.    A 1998 high school graduate and admitted "working stiff", he's enjoying his time in Fargo.    Younger officials have routinely started officiating matches in high school, whether it is to make some extra cash that can be hard to come by at the age.    He's rated as an M1, the grading system by the United States Wrestling Officials Association.     The entry rating is an M3 then as an official works more state events and some kids level regionals, the rating can be upgraded to an M2. More regionals at the junior level will lead to an upgrade to an M1C, the level needed to officiate the Cadet and Junior Nationals and opens the door to officiate major national events on the way to being an M1.  The highest U.S. rating, an M1E can be attained after the U.S. Nationals in Las Vegas.    "I want to do this for as long as I can. This is my hobby," Brablec said.    Socializing among coaches and officials is a frequent occurrence, and Brablec concedes that having more and more younger officials makes conversations flow in a different direction.    "We have a good time on the mat and off the mat. The younger refs are the future of this event and we're training to be the older guys one day. It's like a fraternity," Brablec said.    Josh Kuisle of Fairmont, Minn. is 22 and officiating his third tournament in Fargo.    He still competes in open tournaments and will be heading back to Buena Vista University in Storm Lake, Iowa, where he plans on wrestling again.     He's here, like Brablec, to move up, have fun and enjoy the wrestling, regardless of his more seasoned colleagues.    Kuisle is an M1.    "I've got my M1 and now I can learn from a bunch of different guys out here and get a lot of added points of view," Kuisle said.    "The younger refs have a bit more in common with each other than the older guys, but you learn a lot from refs like Rick Tucci, who's been around for a while," he said.    Rusty Davidson of New Mexico is also from the old guard of officiating. He puts on the athlete and coaches clinics before each tournament is a liaison of sorts between the officials and coaches.    He sees a definite advantage to younger officials on the national stage.    "Our improvement is no different than USA's developmental athlete program and the developmental coaches program. We're improving as well with developing good officials. We're leading the world in that aspect," Davidson said.    To officiate at the Cadet and Junior National level, you must complete your junior eligibility. The youngest official is working Mat 18; Davidson has known him all his life.    Sterling Davidson, Rusty's son, is 18 and officiating his first tournament.    "Just the fact they (younger officials) want to be involved in a very busy time in their life says something. Some are in college, starting families or joining the workforce and to do this it says a lot about what wrestling did for them as kids," Rusty Davidson said.     Davidson and many other wrestling enthusiasts have similar thinking in respect to the sport.    "Wrestling is the one place in American life where there's still a bit of honor," he said.    Akil Patterson, 20, plays on the offensive line at the University of Maryland's football team. He's back for his second tour of duty in Fargo. He's a former Gorrarian award winner (most falls, least time) in Greco.     "To see young guys like that out here is really refreshing," Davidson said.
