Manny Diaz decided someone else needed to call Miami's defensive plays. He chose himself.

The Hurricanes' head coach - and former defensive coordinator - will call the plays on that side of the football in 2021, he said Thursday, while announcing a slew of other changes including the return of Jess Simpson to coach defensive line. Simpson had that role at Miami in 2018 before leaving for the Atlanta Falcons; after two NFL seasons, he returns to Coral Gables.

Blake Baker will remain as defensive coordinator, though Diaz will assume the bigger role for games.
