If my office is any clue, there might be a bug or two going around that might've put a good number of them on the back foot. Also, various teams might be at different points in their training. I don't put a huge amount of stock in early season duals, but, the records of the individual wrestlers for Wisconsin will obviously negatively impacted by this.
Great example of this early season craziness vs late season results from 2022:
Penn State 20 - Penn 16 (12/3/2021)
Penn State 29 - Michigan 6 (1/21/2022)
