In 2007, when Thomas was coaching the New York Knicks, Madison Square Garden executive Anucha Browne Sanders alleged that she was sexually harassed by Thomas. Although Thomas maintained his innocence, a jury found that Madison Square Garden, the owner of the team, improperly fired Browne Sanders for complaining about the unwanted advances.
"I will own up to what I did and the mistakes that I made, but I can't own up to things that I didn't do," Thomas told ESPN's Hannah Storm in an interview that aired on SportsCenter on Sunday. "... I did not call her derogatory names. Just didn't happen."
Thomas said he had "very, very limited actions or conversation" with Browne Sanders during his tenure as the team's coach and president from December 2003 to April 2008.
The jury ruled that Browne Sanders was entitled to $11.6 million in damages from MSG and MSG executive chairman James Dolan.
Thomas said no appeal was made so all parties could "try to move on."
"That was just the decision that was made at that time," Thomas said. "... I can't carry weight or water for something that I didn't do. And, as I said then and I'm saying today, it didn't happen."
Although Thomas was not found personally liable, a portion of the settlement ($6 million) was awarded for the jury's ruling that Thomas aided and abetted a hostile work environment. The rest of the money was awarded because Browne Sanders was found to have been fired for complaining about the environment.
Thomas and Madison Square Garden have disputed the jury's findings.
"It's a rather thorny issue for all of us," Thomas said. "That was a terrible time for myself personally and all families involved. Again, I take full responsibility for the actions and behavior of the Knicks' players when I was there as president and coach.
"... I wasn't the president of Madison Square Garden. I was the president of the New York Knicks. That being said, what went on at Madison Square Garden, if I had any responsibility in it in terms of managing my players, their behavior and actions, again, I take full responsibility for that. But Anucha Browne Sanders didn't work for me, I didn't fire her, we didn't work in the same place, and Madison Square Garden has taken full responsibility for their environment and what happened there."
Thomas denied that he's using his position with the Liberty as a step to getting back with the Knicks.
"First of all, Phil Jackson is a great basketball mind, and the Knicks are in great hands," Thomas said. "And Jim Dolan speaks to Phil Jackson about the New York Knicks, rightfully so."
Meanwhile, Thomas is trying to move on with his new career as president of the WNBA's Liberty. He had applied for an ownership interest in the team, but that consideration was suspended indefinitely after an agreement by the league and the Liberty.
"I'm really happy here," Thomas said. "I like what I'm doing. I'm not looking to do anything other than what I'm doing now. I'm good. I'm in basketball. As long as I'm in basketball, I'm OK.
"... As an athlete, you're always taught to be the best you can be, and you try to get the best out of yourself. I want to max out as a person. I want to max out as myself, whatever that is. I want to be the best me that I can possibly be. I don't want to ... when I die, I don't want to look back and say I have potential to be. I want to look back and say, I was."
