Q is bullish and will not backdown, a pleasant change from Bryn/Mills, except Mills would take the charge. Regardless, I see the Spurs fighting for every possession. Q and Tre as backup PGs is pretty solid. This might be unpopular, but I would start Vassell over Murray for obvious reason. Vassell is a better shooter and potentially better 2way than Murray.
White, Murray, Quindarry
Vassell, Lonnie, Mills,
Demar, Keldon, Diop
Aldridge, Gay, Luka
Poeltl, Eubanks
The small ball would be even nastier:
White
Vassell
Keldon
Demar
Aldridge
