OK, now, if you want to win, and I say IF, you play a lot of minutes to anyone who happens to be hot and unless there is some very unusual circumstance, you give a lot of minutes to your big studs because they can break loose at anytime,
Now what do you do when your #1 stud scores 10 points on 4-7 shooting in the first quarter? 4-7 is statistically almost off the chart for this particular shooter. ALMOST. I think you can merge both principles and play him A LOT more than usual. So what happens? Nothing which either means Smart doesn't agree with my reasoning or he is unaware of how this guy is playing.
Edit: the truth may be that Smart knows no other way of coaching than using unit ball. Any change from that leads to a horrible headache from the dissonance it leads to.
