The word order of assistant and coach makes a difference. Assistant coach vs coach assistant.
It appears that he may be the latter...
ROW 6: James Urban, Wide Receivers; Paul Guenther, Linebackers; Ken Zampese, Quarterbacks; Brayden Coombs, Offensive Asst.; Travis Brammer, Video Director; Hue Jackson, Asst. Special Teams/Asst. Defensive Backs; Chip Morton, Strength & Conditioning; Paul Sparling, Head Athletic Trainer; Jim Anderson, Running Backs; Dan Willen, Asst. Trainer; Nick Cosgray, Dir. Of Rehabilitation/Asst. Trainer; Nick Siciliano, Coaching Asst.
Not a lot of love from OSU fans...
