3 things: I never knew Saclain was so young, I recently read Peter Roebuck though the Waughs didn't like Law and thought he was an upstart and 3 didn't Asif get banned for drugs too at some point?
Calling out Jana Pittman feels a bit harsh considering the reason she never got to win at the Olympics was due to injury, twice. Sure the whole thing turned into a soap opera, especially in 04 but it is hardly her purposefully and knowingly wasting her God given talent.
I think you missed the point that Nannes makes, you must infuse a side with both young and old so the young can learn off the experienced. It doesn't mean sack all the older players bar one and fill the team with 'potential'.
While I agree with you that in the past this mix hasn't been done, the current team has slowly adopted the mantra. Guys like Smith have been placed under Clarke, Warner under Rogers, Faulkner under Watson and we have a rich crop of young fast bowlers who have been floating around the side for a few years now.
