There was an article in associated press covered by yahoo sports that Lincoln Riley and Grinch are both well on their way to turning around the defense..actually pretty funny to read as its based on new recruits and a new philosophy focused on ball hawking and turnovers. They mention that Grinch helped get OSU to the Rose Bowl?? hope the link works
