Schmidt said the greatest stars reached the top through hours of practice doing the same thing over and over again until it became muscle memory.
"Have a look at [basketballer] Michael Jordan. How many hours did he practise doing the same thing?"
But asked if football players today were a worse kick than those last century, Schmidt said it was hard to compare because the sport was constantly evolving.
"I'd almost say they were more skilful now because it's a full-time job so they're touching the footy more. But it is frustrating to see the goal-kicking percentage not increasing with that skill level as well."
