Sports in general isn't like it was 20 years ago. I think with more athletes specializing in one or even two sports, the amount of work needed has increased. It's not enough to attend a week long summer camp, show up in November, and only have your teammates in the room as your only practice partners. There are outliers that can do it, but not many.
I think that if you want to be a state placer, you need to put in the work year round. Practicing at least 3x week, attending your HS open room, traveling to compete, practice at an academy/club throughout the week.
I don't think the "average" wrestler has that commitment. They may make their HS varsity team, but I doubt they see any kind of placement.
