Nene is one of the smartest players in basketball. Most of the rest of team is a collection of the dumbest. Led by Jordan Crawford. And the guys that aren't that dumb are either injured (Wall, Booker) or aren't NBA caliber players (Singleton, Vesely).
Any issue with Nene will show up tomorrow or the day after. Given the team's history with injuries (even this particular injury - remember Mark Price's glorious year with the Bullets? He had plantar fasciatis and played like 5 minutes that year), I wouldn't be suprised by the worst possible outcome.
