The Los Angeles Lakers seemed to have cracked the code when it comes to using the G League for development. However, not as many organizations are as successful.
Far too often in the G League coaches are vying to be promoted and prove themselves with wins and the focus is not always on developing their players. They opt to play the veteran G League and former NBA players on their roster to ensure wins. This and other facets of the G League make it “not yet” the development league that it strives to be.
One NBA Trainer, who is friends with coaches and got some feedback on playtime decisions in the G League, told me that it is really up to the NBA head coach and GM’s who plays when on the development team.
