Just a day before his own birthday, Under Armour athlete Derrick Williams evidently feels like giving back to his fans, as the Timberwolves forward is dropping off signed PEs throughout his hometown of La Mirada, California. Williams is then giving clues via his Twitter account as to the locations of the shoes. So if you're in the area, be sure to follow the former Arizona Wildcat here.  Pretty refreshing to see an athlete blessing his fans, especially so close to his birthday.
