Northwestern has officially hired Lou Ayeni as running backs coach and recruiting coordinator. On this first day that FBS programs are allowed to add a 10th assistant coach, Ayeni leaves his role at Iowa State, where he worked for four seasons -- the past two under Matt Campbell as associate head coach and running game coordinator. Ayeni played running back and safety at Northwestern and began his coaching career as a graduate assistant at the Big Ten school. Veteran Matt MacPherson moves for the Wildcats to special teams coordinator and cornerbacks coach under Pat Fitzgerald.
