When asked about Lillard's endorsement, Booker said the following, per Evan Sidery of Forbes and Bright Side of the Sun:
Booker is averaging 26.4 points on 49.7 percent shooting for the Suns this season. He dropped 27 points in a win over the Golden State Warriors on Wednesday.
He was not happy about his initial All-Star snub, as noted in an interview captured by Duane Rankin of azcentral:
Duane Rankin @DuaneRankin
#NBA is different from the game I fell in love with at the beginning of all the best players being in the all-star game.” #Suns Devin Booker after #NBAAllStar snub. “Growing up watching that and now it’s an entertainment, drama, political-filled league.” https://t.co/DMyBAaGWxH https://t.co/hEmqMfgT9F
Booker did tell Fox Sports Arizona that he would "probably" go if asked but needed to speak with his family:
At the very least, Booker has an endorsement from three-time NBA champion head coach Steve Kerr, who's coached All-Star teams twice.
NBA commissioner Adam Silver will choose Lillard's replacement and the substitute for any other player who hypothetically may miss the game for whatever reason. The replacement must be from the same conference.
Memphis Grizzlies point guard Ja Morant figures to be Booker's top competition for a spot. The rookie has led the surprising Grizz to a 28-26 record and a current top-eight spot in the Western Conference. He is averaging 17.6 points and 7.1 assists.
