If I've said it once, I've said it a million times. I refuse to panic about an 18 year-old in the NBA, and Noa Essengue is no different. He's played six minutes in his NBA career. Six minutes. Those were six very bad minutes, I know, but they were still six minutes. Three hundred sixty seconds (I did that in my head), a literal blip over the course of an NBA season. Obviously, no conclusions can be made about Essengue yet.
However — it would be nice to know what the plan is with him going forward. Playing a guy two minutes in a game is almost worse than not playing him at all; showing anything in such a small window is nearly impossible, and the pressure to immediately contribute is pretty unfair to put on such an inexperienced player.
