When we last saw Quinn Cook, he was being forced into more duty than he should have had to see in the NBA Finals for Golden State, but injuries forced him into that role and Cook shot just 37.9 percent overall and 31.3 percent from three. However, for the season the Duke sharpshooter averaged 6.9 points per game shooting 40.5 percent from three — the Lakers need that kind of floor spacing, so they have signed Cook, a story first reported by Chris Haynes of Yahoo Sports. Lakers GM Rob Pelinka learned his lessons from last summer and has worked to put more shooting around his stars LeBron James and Anthony Davis.
