Michigan Football program confirmed the hiring of Co-DC Mo Linguist and Safeties Coach George Helow. We looked into Mo yesterday, here is some background on George.
George worked as a intern or defensive graduate assistant for Saban at Alabama, Florida State, and for Kirby Smart at Georgia. Helow's then moved to Colorado State in 2016 and became the Safeties coach until 2019. He then spent last season at Maryland as the OLB coach. George worked with new DC Mike Macdonald at Georgia and this is clearly his choice.
Both coach Nua and BJM will remain on staff.
