...yes the data made up of physical measurements which was all available on draft day and all says exactly nothing other than how high off the ground a player can reach with his fingertips while standing with his toes on the ground. Riveting.
For all you know I may have the standing reach of a... very tall person ... but if I don't know how to close out on a shooter without fouling, where my help defense is so I can cheat to one side or the other to force them baseline or middle, and how to identify a pump fake and recover without taking myself out of the play then me and my taradactyl wingspan won't get out of the G League. It's hard for me to take your use of this data seriously when you completely ignore the mental aspect of defense which is arguably more significant than any physical attribute.

and I’m not ignoring the mental aspect of defense. From any draft class about 20 players stay in. Have you considered at that level it takes both the mental and physical tools to join such elite company.
