What happened to Dario Saric?

He went from a 6th man a couple years ago to unplayable even when the Nuggets go all-reserve in a blowout loss.

I remember when he came to Denver that I finally thought Jokic got a reserve that could play meaningful minutes and contributes.

But we play DeAndre Jordan, we play Ronaldinho, we play Adele, we play DiCaprio.

But no Saric? What happened?
