Granted, it hasn't been put in the best position and the most promising of it hasn't been given a chance period, but Spurs fan overrate the youth.
There isn't a single sure fire core building block, let alone centerpiece. Look around at most average - bad teams, almost all have better pieces.
Most seem excited about Murray, but the reality is his metrics read like that of a role playing center. In terms of the things a point guard needs to excel at to be a star, he's not a natural at one and even with some improvement, is still below average at them.
If and when this team ends up with a high pick, they need to avoid the mistake of thinking they're set at any particular position or that a specific one is the biggest need and realize that biggest need is high end talent period.
