Wrestler, 6'4" 295 lbs and columbus takes as preferred walker but we didn't offer (not sure what 'offer'means here). Curious since d-line seems to be our big weakness.
As I understand it, there are two paths to becoming a walkon. One path is to get admission to the school by normal means, and to participate in tryouts. The other is to be a preferred walkon, where the athletic department helps you gain admission, and then you bypass the tryouts. Either way, you are still a walkon, and you still have a lot to prove before you earn a scholarship.
