Mark Cuban reveals ‘hard lessons’ over $3.5bn Mavs sale after handshake agreement fell through

Under Mark Cuban’s leadership, the Dallas Mavericks went from a relatively small market NBA team to a powerhouse. This transformation was perhaps best epitomized by their stunning NBA championship win in 2011, when a Dirk Nowitzki-led Mavs defeated Miami Heat ‘s ‘Big Three’ of LeBron James , Dwyane Wade, and Chris Bosh in a six-games thriller. Cuban, who is worth an estimated $6.8 billion per Forbes, purchased the Mavericks in 2000 for about $285 million.
