I think he timed it perfectly. It would be have been better for Australia if he kept on playing up till Ashes.
His international career didn't even start until he turned 30. This is one of those what if thing, imagine how things could have been had his international career kicked off another 5 years ago. The man is a genius, they didn't call him Mr. Cricket for nothing. My most favorite Hussey innings was the bashing he gave to Ajmal in T20, that was just pure magic.
