The Boston Game proved how well he can execute a pass and how to deliver them. There will be future games where he won't do this but for now, I like his cerebral approach.
I will say that Nurk has pretty good form on his free throws. Maybe he corrected a mental issue or maybe since he is trying to improve his shooting range his free throws are becoming easier. As for the minutes thing, everyone's minutes have been down including Dame. Would you say that Stotts isn't trusting Dame to play as much either? A few games he rode Collins in the 4th that doesn't mean that Nurk's stats are hollow.
Nurk has shown the craftiness to use subtle lunges and reaches to cause the handler some indecision. And also the timing to contest at the last possible moment...he's been a little more conscious of avoiding foul trouble, which would explain him not being as aggressive defending around the rim overall.
