The Miami Dolphins have promoted Matt Burke to defensive coordinator to replace Vance Joseph, who left the franchise to become head coach of the Denver Broncos.

"It's obviously an exciting moment personally and for the organization moving forward," Burke said Thursday on a conference call. "It's been a hectic few days. Since Sunday forward, everything kind of happened pretty quickly. So things will kind of sink in. But I'm really excited to get going and help this team move forward."

Burke has a lot of work ahead in fixing Miami's defense. It was an injured and inconsistent group that finished 29th in the NFL in yards allowed. The Dolphins lost defensive starters Reshad Jones, Isa Abdul-Quddus and Koa Misi to season-ending injuries.

Burke emphasized that he wants the Dolphins to be an "attacking defense," something he felt the team had started to build this season.
