I think that's the point. It's something he's developed as he's matured and developed his fitness in an AFL environment. Burst speed and power out of the contest are attributes that can be improved with fitness and strength training especially if he was a late bloomer physically.That’s a thin draft assessment if they say that he doesnt boast the same explosive athleticism as other prospects???
Some players are almost fully formed at 18 like Rowell while others take much longer to grow into their bodies and full abilities. Warner was obviously nowhere near the full package in his draft year hence why he went late.
Its easy for us to sit back now and say oh we should have drafted him but every club passed on him multiple times so he obviously wasn't displaying the sort of explosive movement and lateral agility he's got now.
