Aaron Kniffin, a used car salesman who has worked at both Columbus, Ohio's Auto Direct and Jack Maxton Chevrolet, is the centerpiece of an investigation by the Ohio St. Buckeyes athletic department, according to a report by the Columbus Dispatch. Kniffin was allegedly involved in "40 or 50" possibly shady transactions with football players and their families over the past five years.
This is a separate investigation from the NCAA's look into what Jim Tressel knew about the tattoos and memorabilia scandal bubbling under his nose at Ohio State. This one is only an in-house case at this point, though the NCAA could certainly become involved in this one too.
Thaddeus Gibson is the Buckeyes player whose name has become most attached to this Dispatch report, as paperwork listed the sale price of his two-year-old Chrysler 300 as $0. Quite a few players, salesman and dealership owners are mentioned; everybody denies everything.
