I'd buy that argument if D-1 wrestling hadn't become even more polarized in terms of schools and ADs taking wrestling as a second class sport. Just look at the schools that have dropped or deemphasized wrestling.
I'd argue there are multiple coaches that could take a school with tradition and resources, such as ISU, and elevate them. Dresser's results only highlite how bad KJ was. When you follow that disaster, and the extremely low bar he set, it's not the rebuild you think. KJ was a talented recruiter, he just couldn't coach worth a shit. Dresser inherited a roster with some talented kids.
KD has coached for a very long time, but you know what, Doug Schwab has coached more National champions than Kevin Dresser. That's perspective.
And Virginia Tech hasn't fallen off the face of the Earth since Dresser left there.
