Look at it like this.
You go wrestle a dual, a wrestler will actually wrestle for ~7 minutes. A wrestling practice is ~90-120 minutes. So if you are trying to be "the best wrestler you can be", what is better time spent? I will also say, practice can be fun. Working on technique and seeing it improve feels good. Sparing and live are fun during practice too.
I think HS kids are wrestling way too many matches now. Some college programs have figured it out and are doing less competitions. I do think at some point though, there needs to be some concessions for fans of the sport. PSU and Okie St should absolutely be dualing during the season. Big events like that are fun and build hype around the sport.
