RJW:
This will age me a bit - but I coached wrestling at a little place called Tribune from 1974-1983.
That's where I was introduced to the Northwest Kansas League - very impressed then and now.
When I started coaching I think NWK had the following (almost legends in wrestling history):
St. Francis - Gabel & Jenkins
Oberlin - Buzz Matson
Atwood - Garcia
Oakley - A kid named Samuelson
Hoxie - Either Mauk or Pickenpaugh
Goodland - Rocky Welton
Colby - Can't rembember - Lampe was at the JUCO
And I think Norton was in there - Jake Durham
I do believe that there are several state championship teams included (1-2-3A & 4A) over the years.
Currently, I think the record book shows the NWK league top notch.

Tough League?? I THINK SO
