The most important foundational piece to a successful NBA team is a superstar point guard, and the best way to find that guy is usually in the lottery of the draft.
The point guards who excite execs the most, or seem to have the lowest failure quotient, are those who are a blur with the basketball—pre-injury Derrick Rose, Russell Westbrook and John Wall types. The strategy is not always fool-proof. The jury is still out on some recent picks sold in the Rose-Westbrook-Wall mold such as Emmanuel Mudiay and De'Aaron Fox, but that type of athlete with burst is usually a good starting point for finding the closest thing to a surefire hit.
