Sure, but equally your leaders need to lead. Clarke should be setting the tone from ball one. I'm not having a go at Paine - I'm a fan - but the days of Geoff Marsh openers are long gone. He might be more expansive than Marsh but he doesn't have the explosiveness or the strokeplay required. Strike rate in ODIs and List A of 68. Not good enough when the field's up. Let him bat at 4/5 and push singles to long-on. It's a cop-out for Clarke to be doing that. And when Haddin's fit Paine shouldn't even be in the team. I reckon you need one explosive guy, one strokemaker, a la Gilchrist/MWaugh. I don't mind giving a young bloke experience at the top of the order with a long term view but if we want to win the World Cup I'd go with two of Clarke/Haddin/Warner/Marsh.
Selectors are a massive part of the problem. Trevor Hohns had no trouble tapping the shoulders of blokes with far greater pedigree than he, but I doubt the current panel has the same amount of sack. Losing AB to the sponsor conflict hurt. Greg Chappell can't take over soon enough.
That said, cricket is still a great game. We all just got complacent with winning. We miss the Windies of the 80s in retrospect, but we hated them back then. A great test match only has one rival in world sport, and we all know what that is.
