I can tell you from experience that parents are afraid of freestyle and Greco. It's not something that started recently either. I wrestled in the late '80s. My mom had to let me wrestle freestyle because it was all we had for "club" wrestling back then, but she absolutely would not allow me to enter a Greco tournament because she didn't want me injured. (hate that I missed out on that fun) Now fast forward to my son we got him into all styles of wrestling as soon as he was allowed. He loves freestyle and Greco season more than he does high school season. It is a mind set that has to be started in the home with the parents allowing their kids to wrestle. If you ask college coaches wouldn't most say they want kids with backgrounds in all three styles? Here would be an interesting stat to pull up, find out what the percentage of kids wrestling in D1 schools wrestled only folkstyle. We may or may not be surprised as parents how many kids are not going to cut the mustard, so to speak, by not experiencing the international styles.
