I don't know....there's obviously one issue in terms of ceiling of each player. I, and I'm sure many others, are just really big on JV's ceiling, and given the type of kid he is, don't think he'll struggle to get there.
Then I think there's a wholly different issue about team-building, and this notion as posited by Simmons as being the good way to build a team. The problem with that is that well run teams don't follow that model. Teams like OKC and San Antonio hang on to their young, high potential assets often for as long as they can.
And this brings me to my biggest issue....I feel like a lot of the people, using the same rationale, would've been the type to trade Harden away for Perkins when that happened for OKC. At the time you have one of the best defensive Cs in the game for a young SG coming off a very average rookie year. The former would fill a great need, and the latter hadn't yet proved to be that missing piece or an all-star player.
