Later years
Mandich was the radio sports talk show host on WIOD 610 AM from 1983 to 1987, and joined WQAM 560 in 1987. He also did color commentary on Dolphins radio broadcasts on which he was teamed with Jimmy Cefalo and Joe Rose. He was known for his trademark soundbite "All right, Miami!" When he gave out the call-in number for cell phone users, he playfully told his radio listeners to call "if you're riding around with the windows down." Diagnosed with cholangiocarcinoma, a cancer of the bile duct, in early 2010, Mandich became absent from his afternoon show. In the fall of 2010, the terminally ill commentator returned to the broadcast booth for his final season of game-day color commentary.

Mandich died from cancer in April 2011 in Miami Lakes, Florida, at age 62.

Shula announced at the service that Mandich would be added to the Miami Dolphins Honor Roll — a ring around the second tier at Sun Life Stadium that honors former players, coaches, contributors, and officials who have made significant contributions to the Miami Dolphins franchise.
