• He said great players share a single-minded daily focus on winning, and denied any financial motive for the Doncic trade.
• He rejected the theory that the trade was a first step toward moving the club to Las Vegas.
• On becoming Sands chief executive, he credited his predecessors and said the plan is to keep investing in properties, staff and host communities.
• Announcing Ujiri, he called him one of the leading basketball executives of his generation.
• In a court filing, he argued there was no live arena opportunity to offer Cuban yet and that disputes must go to confidential arbitration.
• He told The Athletic the arena and any casino resort will be built apart, since the site cannot fit both and timelines differ.

• He personally owns under 1% of the company he runs.
• The families' option could cut Cuban from 27% to 7% of the Mavericks by December 2027. In October 2026 he said the group would look to use it over time.
