After looking like a shell of his once all star self, Kristaps Porzingis finally has a diagnosis for his sickness that hampered him since March.

Brad Stevens shed some light on the mysterious illness that plagued Kristaps Porzingis during the Celtics' playoff loss to the New York Knicks.

The Celtics' big man had dealt with an illness during the regular season, so it seemed that it lingered with him. It clearly impacted Porzingis while on the court, and he simply couldn't provide Boston with the production that the team needed. After Game 6, Porzingis addressed the illness, admitting that he wasn't even sure he knew what it was.
