As a wrestler from Kansas (Abilene '00), coaching in Texas I see both sides. One thing that could be a contributing factor in some states better performance is the freedom of teams to practice and travel as they please. The team I work with had mandatory practice in september and regularly travels out of state.
I think that Kansas wrestling doing so well with so many constraints is a testament to its athletes, coaches, and boosters. I also miss the community that is unique to Kansas wrestling. Even though I am in Texas, I am very proud to have Kansas-USAW roots!
