Mark Cuban wants to make one thing perfectly clear: he did not demand or even ask for City of Dallas dollars when deciding where to plant the Mavericks' new training facility.

Far from it, he said.

"In terms of my negotiation with the city and playing one municipality off another, it didn't happen," Cuban said. "I didn't ask for a penny. I didn't want a penny. I didn't hold anybody hostage and say, 'Listen, so and so has offered me land.' And I was offered land. This city or this municipality offered to do A, B or C. None of that whatsoever. There's a time for that type of thing. But in this particular case, I feel like I owe the city of Dallas more than they owe me. And they don't owe me anything."

Cuban detailed his plans for the new practice facility, which will be located in the Design District across Stemmons Freeway from American Airlines Center, for the first time after a reading-initiative appearance at a Dallas Public Library on Tuesday. He said it's far more grand than simply a practice facility.

"It's going to be amazing," he said. "It's really a three-step process. We've got a little under 100,000 square feet that we're going to renovate now that hopefully we'll start using before the summer is over and training camp starts.

"I'm not committing yet to having training camp there. We'll have to make sure everything's done and working. But the first step is to put in a couple courts, put in facilities, make it comfortable for the guys, add the things we didn't have enough room for (at AAC). That's step one. That will work for a couple years."

Step two involves a new building that will house more than just a state-of-the-art practice facility.

"We've got almost 14 acres," he said. "Hopefully [it's] going to be a six- or seven-story building that will replace what we're doing now and be a much higher-end practice facility that is built for hospital specifications and we'll be able to do a lot more.

"Longer term, hopefully there will be a much larger building that over the next 10 years will be able to host a stadium, or arena, 20 floors up or something so there's a view of Dallas when I'm old and crotchety."

Cuban obviously could have taken his practice facility and future plans for an arena to the suburbs or a different part of Dallas. But he elected to stay in the downtown area because he feels such a connection to the area.

The Mavericks' lease at AAC runs for another 15 years.
