“As the last original owner, I am proud of how far the league has come, and the role we have played in its growth,” James L. Dolan, the chairman and chief executive of The Madison Square Garden Company, said in a statement. “This was a difficult decision for us, which we made after carefully assessing the needs of our business. We are confident that new ownership can build on the foundation we established over these last 21 years, and steward this incredible franchise into an even more successful future.”
On Monday, the Garden announced the departure of chief executive David O’Connor, with Dolan taking his place on an interim basis. Last month, Coach Bill Laimbeer left the Liberty after five seasons to join the Las Vegas team. He was replaced with Katie Smith.
The sale of a marquee franchise by one of the country’s biggest sports operations could be seen as a concern to W.N.B.A., which even after 21 seasons has struggled to find stability and to establish itself in the crowded sports marketplace. But a new owner might be able to give the Liberty a higher profile than they had at M.S.G., which owns not only the Knicks but also the Rangers of the N.H.L.
Though the Liberty have made the W.N.B.A. Finals four times, they have never won a championship. Last season, the team had the best record in the Eastern Conference but lost in the second round of the playoffs.
Two years ago, Isiah Thomas, the former coach and president of the Knicks, became the Liberty president and attempted to buy an ownership stake in the team. But the W.N.B.A. halted the process amid concerns about a 2007 sexual discrimination case against Thomas.
