While the height and weight measurements from the NBA pre-draft camp are interesting and relevant, NBA GMs and scouts also spend a lot of time dissecting the results of the NBA physical combine.
Everyone takes these with a grain of salt. Every year the quote "best athlete in the draft" does NOT turn into the best player in the draft. Teams do take these reports seriously. This is the first objective testing that we have on these guys and sometimes our eyes do deceive us.
