Hextall is Philadelphia's all-time winningest goalie and served as assistant GM last year. Holmgren replaced Bob Clarke as GM during the 2006-07 season and led the Flyers to within two games of the Stanley Cup title in 2010.
The Flyers were eliminated by the New York Rangers in seven games in the first round of the playoffs. They haven't won a Cup since 1975.
Hextall previously spent seven seasons as vice-president and assistant GM with the Los Angeles Kings. The 50-year-old Hextall played 13 seasons in the NHL and had two stints covering 11 years with the Flyers.
I remember the first time at Wrigley Field all of us had the long johns, the turtlenecks and the extra equipment because we were afraid of being cold. Halfway through the first period everybody's ripping everything off and we just ended up wearing what we would normally wear for a game at the United Center.
