Back-to-back games aren't easy. Nor is playing at the FedExForum, where the Grizzlies were 12-1 until the Bulls, playing without Derrick Rose and Taj Gibson, handed them a 103-97 defeat Friday night. Jimmy Butler followed his career-high night with 31 points and Nikola Mirotic sank all six of his 3-pointers en route to his career-high 27 to help the Bulls move to 12-4 on the road.
