NORMAN -- Dana Holgorsen, an offensive-centric head coach if ever there was one, handed over his West Virginia offense last season to underlings.
Mike Gundy, who loved the X's and O's of the job, relinquished the offensive coordinator duties at OSU after the 2009 season, and the Cowboys have soared since.
Gus Malzahn, whose offensive innovation moved him from the high school ranks to head coach at Auburn in a span of eight years, no longer calls the plays for the Tigers.
The dual role of head coach/offensive coordinator ends up being too demanding. Too time restrictive.
