To be successful these days, any FO needs a cap genius, and someone who really understands roster construction. When those aren't the same person, it's more difficult because no matter how much people talk about collaboration, someone has to have the final say. It's what most people don't know and don't appreciate about Jerry West. He understands the game (and players) better than almost anyone, and he has an uncanny understanding of the money/cap aspect. He has more to do with this current Clippers team than most realize. And their FO people are smart enough to listen to him and not let their egos get in the way.
I don't have any first hand knowledge, but my gut tells me that the easiest way to influence Pop is to move the same basic direction he already wants to go; and pushing in an opposite direction would be career suicide. So I really doubt they put anyone in that position that would do the things you'd like to see him do. He doesn't have the experience as a player that I'd like to see him have to really understand players and roster construction, but I think he must be a pretty bright guy. SA isn't the first place he's been promoted, so some other people saw something in him.
But the league is full of bright guys. You're looking for a savant. I don't think he's that. But if I'm being honest, the reason I don't think so is that he took a position where he doesn't get to be his own man. The real geniuses won't settle for something that even looks like a coattail assignment.
