I give three years that are 15 years apart for comparison.
School year____schools wrestling_____rank in sports_____participants____rank in sports
84-85_____________8,273__________________8th_____________248,300_______5th
99-00_____________9,046__________________9th_____________241,579_______6th
14-15_____________10,597_________________8th_____________269,704_______6th
so you can see, there has been no decline in high school participation. Wrestling is holding its own, and as girls wrestling takes hold, I expect those numbers to blossum substantially. We should all support girls wrestling because someday those girls will be fans of the sport and positive to their sons and daughters about getting into it.
