"When you talk about Andrew Symonds it's like talking about Bradman as a batsman or Ponting as a batsman. He's in a place of his own, he's that good an athlete, in many ways like Usain Bolt," Fox Sports quoted Young, who is Australia's fielding coach for a seventh straight summer, as saying.
Young has also had coaching experience with Australia's Olympic baseballers.
"I think he's the best all-around athlete for strength, power and speed in cricket I've seen. Jonty Rhodes was good, real good.
Ricky Ponting is real good, Michael Clarke is real good, but none of those guys have the flat out, brute athletic power and strength of Symonds," he said.
