Center JaVale McGee has secured the Warriors' 15th and final roster spot. Golden State waived guards Cameron Jones, Phil Pressey and Elliot Williams on Thursday to get its roster to the league-maximum 15 players for the regular season. McGee is averaging 5.2 points, on 59.1 percent shooting, 3.3 rebounds and 1.2 blocks in 10 minutes per game in the preseason. In the Warriors' past two games, he has totaled 20 points, on 10-of-14 shooting, six rebounds, two assists and two blocks in 21 minutes. Williams, the only one of the Warriors' original six training-camp invitees to sign a partially guaranteed deal, has missed all preseason after undergoing right knee surgery.
