Callahan said he spoke to former NHL players and current television analysts Martin Biron and Scott Hartnell about the transition from the ice to the studio. Their best advice to him was to try out the television avenue because it gives him an avenue to have his voice in the game.
"You're talking about what you know, so when you get on, feel comfortable with it and share your knowledge," Callahan said. "There will be some time when I'm not completely 100 percent comfortable behind the desk on TV, but I'm looking at it as a new challenge, a new chapter and I'm excited to do it."
Callahan will be living in Tampa and commuting to the NHL Network studio in Secaucus, New Jersey.
As for his health, Callahan said his back is holding up well other than occasional soreness.
"It's more the contact of the game that aggravated my back, unpredictable movements," he said. "Luckily, day to day I'm good. There are days I'm a little bit sore but I'm pretty lucky to be able to stop before it got too bad."
Callahan had 386 points (186 goals, 200 assists) in 757 regular-season games and 39 points (20 goals, 19 assists) in 121 Stanley Cup Playoff games through last season. He also played for the United States in the 2010 Vancouver Olympics and the 2014 Sochi Olympics.
