Dirk Nowitzki seems to receive some of the best gifts from his fans. On Friday, Nowitzki shared a photo on Twitter of a gift he says he received from a fan at the team’s open practice. The photo shows Nowitzki holding up a letter containing a $20 bill. In the letter, the fan says Nowitki has been taking discounts to help the Dallas Mavericks the past six seasons, so the $20 is intended to buy the star big man lunch.
