FWIW: Booker's 71.4 percent 3-pt shooting %age in his first 19 games is the best (minimum avg of one attempt per game) in a player's first 19 career games in the past 30 years.

Only 221st right now on 3pta rate. That should change with time but how far, how fast and why is it starting so low? Trying to avoid one dimensional label or teams prepared and effectively limiting attempts? Is his movement inadequate or is he not getting enough screens and passes?
