JALEN GREEN HEARS the wrath from the old man with the unmistakable, raspy voice.
It's a little less than an hour before the Rockets' shootaround begins, but almost half the roster is already on the Footprint Center floor in Phoenix, running three-man pick-and-roll drills.
John Lucas, the Rockets' 68-year-old assistant coach, provides running commentary throughout the workout, usually while standing on the baseline. Green, the Houston Rockets' prized rookie shooting guard drafted No. 2 overall, is Lucas' primary target. Green had just picked up his dribble near the free throw line and nonchalantly scooped a lefty lob pass when Lucas peppers his 19-year-old pupil.
