After retiring due to injury, he joined
MSG Network's hockey coverage staff in 1983, and was the
color commentator for Rangers games from 1986–87 to 2005–06, working with
Sam Rosen. He was known by the nickname "J.D.", became one of the most prominent color commentators in the sport, and his hockey insight is so well respected that he currently sits on the
Hockey Hall of Fame selection committee. Long-time network TV partner
Mike Emrick also sits on that committee, and the two shared the 2004
Lester Patrick Trophy for service to hockey in the U.S. In 1994, the Rangers won the Stanley Cup for the first time in 54 years, in the highest-rated game in MSG Network's history; Davidson announced, "No more 1940, it's gone!" Davidson has also contributed to NHL coverage on such national
television networks as
CBC,
Fox,
ESPN/
ABC,
NBC/
OLN,
SportsChannel America, and
Global. He served as the lead color commentator, alongside lead play-by-play announcer
Mike Emrick, for the
1996 World Cup of Hockey, the
NHL on Fox from 1994–1999, and again for the
NHL on NBC and
NHL on OLN from 2005–2006. Davidson was known for his signature phrase "Oh, baby!" He was also featured in full motion videos shot for the
EA Sports video game
NHL 97. He co-authored the book
Hockey for Dummies (of the popular
For Dummies series) with sportswriter
John Steinbreder. Davidson returned to the broadcast booth to broadcast select
Columbus Blue Jackets games starting in October 2024, filling in for
Jody Shelley. Davidson returned to the booth with Sam Rosen on April 9, 2025, in honor of Rosen's final season broadcasting. ==Executive career==
