According to the NFHS data (boys only), Texas and Oklahoma ranked #1 and #2, respectively, in number of wrestlers added from 2010/11 to 2015/16. In contrast, nine states experienced a participation decline of more than 14%. Both Washington and Oregon participation declined by nearly 21% over the period.
but it appears having more teams than the wrestling population can support in some areas is one of the problems here.
Not buying this. If a person goes into a tiny Oklahoma town (or any tiny town for that matter - I know so many small towns in Oklahoma have excellent participation), they are not having an effect on a program somewhere else. It is making wrestling available over a larger percentage of the country. A program in Duncan is not detrimental to a program in Lawton. (I am from Texas and am aware of the situation in Oklahoma. In Texas, each high school that adds wrestling does not diminish from the next high school that already has wrestling. Each high school is their own isolated "world" and growth or failure is contingent upon what happens within that high school.
