Jagr, who will turn 41 midway through next season, returned to the NHL in 2011-12 after three seasons playing in the KHL. He scored 19 goals and 35 assists for Philadelphia in 73 games, adding a goal and seven assists in 11 playoff contests.
For his career, he's netted 655 goals and 988 assist for 1,643 points. That puts him eighth all-time in points — the leader among all active players — and 11th all-time in goals and 12th in assists.
This will be his first time playing with a Western Conference club.
"I don't think there's any question he still has game in the tank," general manager Joe Nieuwendyk said on a media conference call. "He had a terrific season with Philadelphia."
Nieuwendyk said he and senior advisor Bob Gainey had a lengthy conversation with Jagr on Monday, and that the veteran was intrigued by the possibility of finally playing in the West, as well as meshing with the club's young offensive talents such as Jamie Benn and Loui Eriksson.
The Kladno, Czech Republic native captured the Hart Trophy as league MVP in 1998-99 with Pittsburgh and won two Stanley Cups with the Penguins earlier that decade. He's led the NHL in scoring five times in a career, tied for fourth most among all Art Ross Trophy winners, in a career that has also included stops with Washington and the New York Rangers.
Nieuwendyk in the last two weeks has acquired left wing Ray Whitney, another 40-year-old, as well as centres Derek Roy and Cody Eakin, along with defenceman Aaron Rome. They parted ways with, among others, forwards Mike Ribeiro and Steve Ott, as well as defencemen Sheldon Souray and Adam Pardy.
In helping facilitate the bold moves, the GM credited new Stars owner Tom Gagliardi, the Vancouver native who took over the club in the spring. The Stars were forced into bankruptcy at the end of Tom Hicks's lengthy tenure as owner.
"Tom has come in here and moved the clouds away from our franchise and has put us back on the map and I think the moves that we've been able to make the last few days are an indication that we are back as a real relevant franchise and we feel extremely pleased with what's transpired," Nieuwendyk said.
Nieuwendyk said he didn't anticipate any more major moves from the club in the coming days.
Jagr, who earned $11 million at the peak of his career, made $3.3 million with the Flyers last season.
