Is he playing it smart? As 538 pointed out a few weeks ago, Bernie is still struggling to appeal to non-white voters

He at least some support with minority voters if he is going to get the nomination. Part of the appeal of Bernie is that he is supposed to be fairly no-nonsense and tell it like it is. But by avoiding talking about race, doesn't he drive away the minority vote because it means he either thinks that a) race isn't actually an important issue (which I think many minority voters would chalk up to out of touch white privilege) or b) he's tiptoeing around the issue for politics reasons just like any other politician, so much for no-nonsense.
