That Higdon's carries might have been Harbaugh showing some ankle to Kareem Walker, the nation's #1 RB and OSU commitment that attended the game as an official visitor. Had he played yet this year? I am sure he earned it with effort in practice and he definitely brings that Clarence Williams, scat-back, look to the offense, but I think giving a true frosh some serious carries also shows something to Walker about playing time for freshmen RBs.
