It's actually Oklahoma State.
"Oklahoma State: Mike Gundy has announced the hiring of Dan Hammerschmidt and Eric Wolford. Hammerschmidt, who coached the running backs at Houston last season, will fill a defensive assistant position and Wolford, the former Youngstown State head coach, will be an offensive coach. Receivers coach Jason Ray will not return. As we understand it, Hammerschmidt will coach the corners and Wolford and Bob Connelly will work together on the offensive line. The nine are now full for Oklahoma State."
