Yeah... whilst I agree that the tests themselves aernt a true indication of the kids physical abilities compared to his peers they do serve to give the club an indication of the kids athletesism. IMO you have more to work with if you have a kid that is an athletic talent as well as a decent footballer, theres more scope for improvement.
If he is a decent footballer but lacks the physical tools (height, reach, leap, speed etc...) he will generally struggle to improve at afl level.
I agree with that but I dont think that these sorta tests really translate to being an athlete of the footy field. Jack Watts last year was the second fastest over 20m in a time that would have had him as the fastest of this years bunch, yet in the few games he's played he's looked as athletic as a crab. Lucas may be able to run around stationary poles faster than someone like Jetta, but on the footy field Jetta is far more evasive and agile.
