Wrestling in PE

I have always wondered why wrestling was never common in physical education. Personally i am a wrestler, so i am probably pretty biased about the subject, but if traditional classes contain basketball, baseball, football, soccer, and volleyball i do not see the difference in having wrestling in the curriculum. I am currently enrolled in Slippery Rock University and majoring in Physical Education. When i graduate and hopefully become a teacher i plan on including wrestling into my curriculum. I believe the sport of wrestling can teach students a lot more then just skills but also discipline and body awareness. It would be intended for high school and middle school students.
