Leonsis insists that it is time for the Wizards to prove their potential by earning a spot in the playoffs.
"I'm tired of losing," Leonsis told reporters at a press conference. "It's not a lot of fun coming to games knowing, 'This is going to be a tough night.'
"We're just at that point now, it's the fourth year, we've retained our players, we've added players, we've spent a lot of money. And I expect us to be a playoff-calibre team.
"I think our fan base expects that too and that's the pressure I've placed on our organization, that we have to meet the expectations of our fans — and it's time."
The Wizards begin their season against the Detroit Pistons on October 30.
