SAN FRANCISCO – Glenn Robinson III joined the Warriors partly because he has been peaking in their direction for a couple years and partly because Draymond Green, the team's busiest recruiter, has been in his ear. Mostly, he came because the summertime departures of Kevin Durant and Andre Iguodala, as well as the serious knee injury sustained by Klay Thompson, created a job opening that speaks to him. The Warriors need a competent small forward in their starting lineup, someone who occasionally can make a shot, embraces defense and understands teamwork.
