"There's no better Gamecock than Marcus Lattimore", Muschamp said in a release.
But Lattimore has never left the football world completely, and SC coach Will Muschamp has wanted to bring Lattimore onto his staff in some capacity. "He has a coordinator's mentality and is an outstanding young coach".
Krantz is a 2009 graduate of the University of Northern Colorado with a degree where he began his career as a student assistant for the defense from 2007-08 before becoming the linebackers coach at his alma mater from 2009-10.
Krantz spent the past two seasons as a defensive analyst at SC.
Muschamp, who has been coaching in the SEC since 2011, was on a one-year stint as the defensive coordinator for the Auburn Tigers in 2015.
As a freshman in 2010, he rushed for 1,197 yards and led the Gamecocks to their first SEC Eastern Division title and was named SEC Freshman of the Year.
Unfortunately for Lattimore, knee injuries ended his sophomore and junior campaigns.
He wanted to get back to SC for a while, especially since Will Muschamp was hired as the head coach, but he was forbidden to do so by the NCAA because he has a foundation that involves some Gamecocks recruits.
Lattimore was one of the most beloved players in USC history.
Lattimore spent three years with the Gamecocks as a running back, rushing for 2,677 yards and 38 touchdowns.
Though the San Francisco 49ers drafted Lattimore in the fourth round of the 2013 draft, he never appeared in a regular-season game. He's now married to the former Miranda Bailey.
