Jim Harbaugh is reportedly adding to his staff.

And he's tapping a familiar place for a familiar face.

The Michigan football program plans to hire University of San Diego offensive coordinator Tanner Engstrand as an offensive analyst, reports ESPN's Adam Rittenberg.

Engstrand, a former quarterback at San Diego State, has spent the last 13 years at the University of San Diego, where he got his coaching break as a graduate assistant under Harbaugh in 2005 and 2006.

He's been a full-time assistant there ever since, coaching the quarterbacks and running backs and coordinating the passing game through the 2009 season.

USD named him offensive coordinator in 2011, and since then the football team has gone 63-18 and won at least a share of the Football Championship Subdivision's Pioneer League six of the last seven seasons.

Engstrand's offenses are among the best and most explosive in FCS, with the Toreros finishing in the top 10 nationally in eight offensive categories during the 2013 season. In 2017, USD finished first in scoring offense in the Pioneer League, averaging 36.4 points per game.

He added the title of assistant head coach in 2013.

As an analyst, Engstrand won't be allowed to work with players on the field during practices or games, or take part in off-campus recruiting, but his work behind the scenes will be crucial.

As of now, Engstrand joins former Minnesota offensive line coach/run game coordinator Ed Warinner, Kevin Lempa, Tyler Brown, Devin Bush, Sr., and Elijah Sandweiss on staff as analysts.

Warinner, a former offensive coordinator at Ohio State, was reportedly added to the staff last month before wide receivers coach Dan Enos' departure. That left Michigan with nine known on-field assistant coaches; one shy of the NCAA-allowed maximum.

Harbaugh is expected to speak with the media Wednesday afternoon.
