The Pistons could make a coaching change this summer.
But it won't involve Coach Rick Carlisle.
Pistons assistant Kevin O'Neill has emerged as a leading candidate to become the next coach of the Toronto Raptors.
The Raptors have asked the Pistons permission to interview O'Neill as a possible replacement for Lenny Wilkens, who resigned in April.
O'Neill is the architect of the Pistons defensive system that has been the league's stingiest the last two seasons.
