One theme in Fake Fundamentals: Volume 2 is the need for more playful practice. In a chapter about dribbling drills, I discuss playful practice and attribute, at least in part, the difference in learning between children and adults to the willingness to play and explore.
The final version concentrates on playful team activities. However, the original, longer version explained my process for developing my dribbling skills in my 20s, which included dribbling against the younger brother and sister (both under-7) of a player who I coached before and after practices. In an earlier version, I also suggested that dribbling against a playful dog is another way to develop handles, as Brianna Finch, head coach at New Mexico Highlands University, dribbled against her dog when she was young before going on to play D1 basketball.
Most people view the video of Jahlil Okafor jokingly, but there is real value in the playful practice.
