This doesn't deserve it's own thread, but doesn't really fit with any of the threads, so maybe it's as good a place as any to put it:
I've mentioned in another thread that there seems to be movement toward convergence in the value of draft picks, especially compared to a generation ago. In other words, it's getting harder to predict where the top players are going to come from in the draft. (This is not to say that drafting later has the same odds for getting a strong player as drafting earlier; the odds are still best to draft early, of course. It's just that the difference between the kind of players you get drafting later compared to drafting earlier is narrowing, especially in recent years). The following graphs, which are based on small research projects I've done, provide evidence for this idea, I think.
The first shows what draft picks the 1st, 2nd, and 3rd All-NBA teams come from, on average. You'll see that there's a great narrowing in the last 10 years especially, with 1st-teamers coming from later and later in the draft. This year's 1st team could easily be as high as a 16.6 average.
The second chart shows the relative value of four first round picks, selected to best illustrate the trend (based on a blend of career win shares and VORP scores). Top picks have generally lost value over time, mid-round picks have kept their value somewhat, lower-round picks have increased their value. (In both graphs, lots of data smoothing has been employed to help highlight what seem to be real trends.)
