I agree about separating conference opponents, but when one conference sends about 1/4 of the participants to a tournament it's going to be difficult to do. with D1 down to 70 some programs and many schools all trying to get a top notch strength of schedule, rematches in the NCAAs is going to be more and more likely. the upshot is the more guys wrestle the same people the more accurate the seeds will be.
Ashnault wrestled Hudson very early last year (i think it was the 1st D1 dual, before the Grapple at the Garden) and had a tough match. Hudson is a great athlete but he appears to have plateaued with regards to results, while Ashnault has steadily improved. Hudson's last match was a very one sided 8-0 loss to Randy Cruz of Lehigh at the EIWA's, who Ashnault beat convincingly 9-2 at the National Duals a few weeks earlier.
