The Sacramento Kings have a number of rookies and young players just sitting on the bench, collecting dust. Finally, they've sent their two-way players to the G League to get some reps. It's important because the coaches were just wasting their limited time on the main roster.
Two-way contracts allow players to spend time in a season on both the NBA squad and the G League squad. These contracts generally go to younger players, if not outright rookies, who have potential but need more time to hone their skills. But there are limits to this.
An NBA team can only have three players on two-way contracts each season in addition to the 15 regular contracts for main roster players.
