Sure, but that really doesn't change things... it's just gravy. If they were picking #8 instead of #2, then they would have made moves to build a roster to compete for a Top-6 seed? That doesn't make sense. If anything, getting Harper has freed up some assets (like Vassell) you can move to upgrade the rest of the roster.
But the Spurs appear to not be very concerned about PF and backup C... which is going to make it difficult to compete in the west. So, what was the point of getting someone like Fox? There is no need to acquire a Top 30 player so that you can compete for a play-in spot.
