On Saturday, Mobley took another step forward in his recovery. He was able to test his elbow injury, back using his dominant right hand. After practice concluded and many of his teammates were already in the locker room, Mobley was working with team trainers at the basket nearest Bickerstaff’s office. Mobley started with light, right-handed shooting — baseline jumpers, free throws, mid-rangers. Even though the workout wasn’t anything extensive, it was a noticeable change from days earlier in Brooklyn.
