Isiah Thomas is back at Madison Square Garden. Thomas has been hired to be president of the New York Liberty of the WNBA. Thomas also will have an ownership stake in the team. Garden CEO James Dolan, who owns the Knicks and Liberty and is an unflinchingly loyal Thomas supporter, said he began discussing the role with Thomas in the fall and he has been pleased with the results. “Now, we’ve agreed that it is time for him to take a lead role with the team as president, and through his ownership interest. He’s an excellent judge of talent, and I’m confident that he will put all of his energy and experience into making the Liberty a perennially competitive and successful team,” Dolan said in a statement.
