My position on this has not changed from a year ago except that my son is just finishing his first high school season. Watching this season go by for my son's team, I am even more convinced that this JV Regional concept would be good for a lot of wrestlers. I have seen kids from the JV team place and even win several varsity tournaments when the first team teammate was out for injury. I still think wrestling should handle this more like track and field where more than one individual could compete for Regional and State competition. I believe that this JV Regional concept is a way it could happen.
I believe you could find a weekend sometime before Regionals to hold the meet. It seems like many teams take a weekend off from tournaments close to Regionals. I am not sure how many should move on to the Regionals, but I would think at least the top two. If it was only two you should have a second place challenge if needed between the second and third place finisher.
I would also let the JV qualifiers points count for team points at both Regionals and State. This is the way it is done for track and field. I think it could work for wrestling too. We all know this would give some teams with a lot of strong wrestlers an advantage at State but it works for track and field. I think it would just be a change that wrestling would get used to. In a sense the State competition should be really more about determining who the best wrestlers are in a weight class. The way it is now some of them might not even be getting the opportunity to compete there. I believe someone posted last year the best way to determine the best team would be a State duals competition format.
