One quote in particular struck me:
we find no consistent statistical relationship between combine tests and professional football performance, with the notable exception of sprint tests for running backs.It means everything surrounding the NFL draft is just for show. With the exception of how fast a running back can run they really have no idea how to test whether someone will be a good NFL player. How much of this applies to all careers though? How many times has a job candidate been hired because of great education/experience and been a complete bust? I wonder if anyone has done any studies on "how to identify talented and productive employees."
