The Orlando Magic are giving strong consideration to a big change in their front office, according to league sources. Sources told ESPN that Magic general manager Rob Hennigan's job is under threat at season's end in the wake of a fifth straight non-playoff season since he was hired. The Magic expected to contend for a playoff berth this season after hiring former Indiana Pacers coach Frank Vogel to replace Scott Skiles and trading for Serge Ibaka on draft day last June. But Hennigan, the league's youngest GM at age 34, wound up trading Ibaka to the Toronto Raptors just eight months after surrendering Victor Oladipo, No. 11 overall pick Domantas Sabonis and another future first-round pick to acquire him from the Oklahoma City Thunder. The about-face on Ibaka was widely seen not only as a concession that the Magic's roster was overloaded with big men but also that they had little shot of re-signing Ibaka in free agency this summer.
