[Chart] Age when drafted matters: PER by Age, Segmented by Age in First Season

Unfortunately, I cannot for the life of me find the original source of this. I do remember spending a ridiculous amount of time trying to dig this up, however, and it still seems weird this info is so hard to find. Saved it a few years ago. If you recognize this let me know!

Of course, there is a selection effect going on here, but it's worth noting that as of the draft this selection has mostly occurred. Possibly some interaction with draft order which wasn't shown here. I will say however that all of ESPN's top 10 are essentially 19, but when looking at future potential in general I think it's useful context for how well, for example, guys like Haugh or Lendeborg or Stirtz (all \~23) may not have the upside you otherwise might imagine.
