I don't understand why they record the 20m sprint and such on a basketball court anyway, surely it should be done out on a football field. The difference between a perfectly flat, hard and indoor surface and soft, ever so slightly bumpy grass shouldn't be underestimated in terms of running.
Thats a good point there's also no real sidestep in the agility test they just change directions and go the opposite way around posts not really a good simulation of a match scenario. They should have to step to the side then continue in the direction they were heading.
