Have your wrestler train for and compete in the Kansas State FS/GR Tournament to be held in Junction City on June 5-6. If he places top three either style, this will qualify him for the Kansas National team which will compete in Fargo (at least this is how it has been done in the past, unless the coaching staff has a different selection process in mind?).
Even if he does not place at Junction City, he should still sign up for the National Team training camp and he will most likely (but not always) be able to find a spot on the team. He can challenge for a spot sometimes, or there are often openings (a kid who placed at State does not intend to make the trip to Fargo), or a kid may perhaps want to do only one style, leaving an opening somewhere.
In all my years of coaching on the national team staff, it was very uncommon for a kid to not be able to find a spot on the national team. While it does happen on occasion, much more often than not a kid can find a spot on the team.
He also could attend a Regional (the closest one is usually in Oklahoma, Southern Plains; but there are others if he is willing to travel) and place top three which would qualify him automatically for Fargo regardless of KS placing.
You could contact Coach Mike Garcia (junior director) at Hutchinson HS for more information.
