What a loaded question here. Lots of fabulous guys have been mentioned on the above posts. In my wrestling days anyone with an Ark City singlet was a beast including Ware, Beeson, and Hernandez (HS National Champion). I coached some dominant guys at Colby (ex. Murray 2x State Champ & DI National Runner-up at Nebraska, and Luedke State Champ & 2x JUCO National Champ & 2x AA at Iowa). I coached against a bunch of dominant guys also that come to mind Kreigbaum & Taplin (Abilene), Gilliland (Hoxie), and Gable (St. Francis). This list could go on forever.

I believe though this post was attempting to determine how Weigel's dominance compares to past wrestler's seasons. I have not seen this Weigel kid wrestle since he was a little dude in Russell when I coached there so I can not compare him to anyone.
But if you are talking most dominant season by a Kansas wrestler - there is no way anyone can compare to the senior year Jeff Boyle from Norton had.
I believe Boyle was 32-0, a state champion and his total wrestling stats were 32 takedowns and 32 pins. No escapes, no near falls, no reversals, no penalty points. Game over, can't be more dominant than that.
