Draymond Green left the Golden State Warriors ' game last night vs. the Washington Wizards with calf tightness, and with the exact timetable for his return uncertain, Steve Kerr is likely turning to one of his young players to fill in for Green.

I spent my Monday afternoon watching the Warriors get obliterated by the Celtics — a 40-point loss, wire-to-wire domination and a stark reminder of just how far Golden State has fallen. One thought kept creeping into my mind: The path Boston took to become the powerhouse it is today is the exact lesson Golden State needs to learn.
