The likes of Fleming, Kasprowicz and, it now seems, Clark might also be able to be said to be better had they gotten more of a chance and been ignored by diabolical selectors less frequently.
And of course with the likes of Johnson, Siddle, Hilfenhaus, Bollinger, McKay even, we wait to see how their careers will pan-out - all are merely starting right now.
