Dedes was born in Panamus, New Jersey. Before working with CBS, he called NFL games on Fox in 2004 as well as the New Jersey Gladiators of the Arena Football League. Dedes was the radio voice of the Los Angeles Lakers from 2005-2011. He was expected to replace Joel Meyers, but signed a contract with the New York Knicks instead.
Meyers now calls games for the New Orleans Hornets. While at NFL Network, he has called BCS games and NFL Preseason Games for the network. He called the 2004 Summer Olympics on NBC for field hockey at the age of 25. This made him the youngest member of an Olympic Game broadcast for NBC. He also called college football and basketball games for Westwood One.
