I don't know if you are just trying to be humble by saying, "crappy washed up wrestlers like myself to walk-on." But that is the wrong attitude to have when making a decision on wrestling in college. Wrestling in college is a big committment and the number one thing that is neccesary to be successful at that level is a good attitude. Humble, yes-negative, no!
University of Kearny at Nebraska, University of Nebraska at Omaha, University of Central Oklahoma, Central Missouri State University, and Truman State University are a few D IIs in the midwest. Bacone, Dana, and Missouri Valley are a few D III's. Good Luck-but remember that the number one thing needed at any level of wrestling is a good attitude. So cut out the self negative talk and get started by lifting, running, and drilling and you will be on your way to a good career.
