When Troy Weaver spoke at season’s end and said, “The assets for the Pistons moving forward are all in house – it’s internal development and growth that will be our focus this summer,” it was easy to draw the inference he was referring largely to the four rookies drafted last November and thrown into the fray immediately without benefit of a typical rookie orientation. He could just as easily have been talking about Hamidou Diallo. At 22, Diallo showed flashes – thunderbolts, at times – of the potential NBA scouts have seen in him since he came on their radar as a 15-year-old on the AAU circuit. In 20 games with the Pistons, Diallo showed the athleticism, toughness and explosive bursts that make him a potentially devastating defender and holy terror in transition and as an attacker.
