I like some of the stuff I've seen from Vesely and Singleton, but in my own opinion I think this team would be in a much better position if they used the 6th pick on Kawhi Leonard and the 18th pick on Marshon Brooks.
Kawhi;s averaging 7 and 5 in just 24 minutes a game and is much more polished than Vesely. I think he could potentially be like Gerald Wallace in the future.
Marshon Brooks would bring badly needed shooting to this team, while shooting a high %. He's like Nick Young but he can actually rebound. I think in the future he could be similar to Kevin Martin. He's already much better than Crawford
