This is incredibly interesting, to me.
Now, my opinion is that the Sacramento Kings will have a very low limit set on the amount of actual input the two fans chosen to participate in their draft will get. I view this as about 95% PR move, designed to get the fans involved with their franchise.
Viewed as such, I think this is utterly brilliant.
A side benefit to this, of course, is that in just about any fan base there will be some fans that actually possess NBA-level analytical skills, but obviously are likely to have limits on the scope of what they analyze (i.e. their own team, and/or other players in the league based, obviously, on their own time and interest).
However, with a focused task of analyzing a limited pool of college players, it could very well be that whomever they choose could, indeed, provide at least some vetting of the Kings' own thinking, or at least some fresh angles and takes on the players available. The caveat, of course, would be that the Kings' process will lead them to two such people.
In any case, bravo to the Kings for this!
Side note: if the Kings really are wanting to use this to tangibly influence their draft decision, well, y'all cray cray.
