The season is too long. I don't know of any other "kids" sports that run 4-5 months.
Actually most competitive leagues of most sports for kids will last as long as folkstyle wrestling season or longer. Competitive swimming for little guys is year round, baseball goes longer then 5 months if the kids are playing fall ball, kids football can go 5 months, gymnastics, volleyball, it goes on & on. One big difference with wrestling compared to baseball or football is the fact that you can take as much time off as you want, as long as it's not in March.
