Rudy Gay was happy to play a role in helping Lonnie Walker IV showcase his athletic skills in the Spurs’ 136-109 romp over Detroit on Saturday night. Letting the ball go just as he passed half court, Gay assisted on Walker’s soaring, on-the-run alley-oop dunk that gave the Spurs a 34-32 lead with 10:13 left in the first half. White also recorded an alley-oop slam in the fourth quarter on an assist from Derrick White that gave the Spurs a 24-point cushion with 9:45 left. “It’s about time,” Gay said of Walker taking advantage with his superior athleticism. “He is an athlete and he can do it, he might as well start doing it…He is getting better at playing the way we know he can play.”
