One week prior to Diaco's departure from Notre Dame, Martin, the Irish's now former offensive coordinator, accepted the head coaching job at Miami (Ohio).
Swarbrick and Notre Dame's administration would consider Martin for the same reasons it would consider Diaco: Martin's familiarity with the roster and coaching staff and his ability to promote continuity within the program.
Yet what makes Martin, perhaps, a more attractive candidate than Diaco is his number of years spent working with current head coach Brian Kelly.
Martin was Kelly's defensive coordinator at Grand Valley State University from 2000-03 before replacing Kelly as the Lakers' head coach from 2004-09. Then, when Kelly was hired at Notre Dame, he lured Martin away from Grand Valley State to coach the Irish's defensive backs before eventually being promoted to offensive coordinator after Charley Molnar departed for the Massachusetts head coaching job.
While Martin possesses all the necessary credentials, his performance as head coach at Miami (Ohio) would be the most significant factor in his potential consideration for the Notre Dame job.
