Following the conclusion of Greco-Roman action on Thursday, 10 wrestlers still had hopes of winning the award.    The Triple Crown is captured by winning the Kids Folkstyle National Championships which took place in April, along with the freestyle and Greco-Roman divisions of the Kids National Championships.    Riley Adamson of Albuquerque, N.M. is on pace to capture his fifth consecutive Triple Crown after winning the Schoolboy division at 85 lbs.
