To wit: Weaver was the only candidate to interview with the Pistons’ owner, Tom Gores, according to a person familiar with the search who was not authorized to discuss it publicly. Beyond maximizing the Pistons’ forthcoming high draft pick and some newfound financial flexibility after the February moves to jettison Andre Drummond and Reggie Jackson, Weaver’s immediate challenges include learning his new terrain and meshing with the various voices in Detroit after spending the last 12 seasons in Oklahoma City. Gores leans heavily on Arn Tellem, the longtime power agent who serves as Detroit’s chairman, and Ed Stefanski, who will remain with the Pistons in his position as a senior adviser to Gores.
