"I am excited to expand my role with ESPN to include games on ESPN Radio," Barry said. "I know I can't fill the shoes of Dr. Jack Ramsay, but I will do my best to inform and entertain our listeners."
"For the past 18 seasons, it was my pleasure to call NBA games on ESPN Radio alongside the late, incomparable Hall of Fame broadcaster, dear friend Jim Durham," Ramsay said. "I'll always treasure our time together and the great games we were privileged to call. Now I look forward to listening to Kevin Calabro and Jon Barry -- both outstanding broadcasters who know the game."
