Dallas Mavericks star Dirk Nowitzki faced the media after confirming his retirement. The 40-year-old German kept his plans secret until the end of his final home game, a 120-109 victory over the Phoenix Suns. Nowitzki brought down the curtain on a career spanning 21 seasons with Dallas, surpassing Kobe Bryant's record of 20 with the Lakers. A sell-out crowd cheered anything Nowitzki did from the start - remembering that he guided the Mavericks to their only championship victory, eight years ago.
