Eleven minutes into the Warriors' 119-104 loss to the Celtics, 22-year-old Omari Spellman stood at the top of the key, surrounded by teammates of a similar era. To the right of Spellman, 20-year-old rookie Jordan Poole stood in the corner, waiting for a pass that never came. Of the five players on the floor, only Alec Burks was born before 1995, bringing a familiar sight for Golden State.
