I love how utterly random your criteria for 'destroyed careers' and 'phantom potential' are.
Dussey, Katich, Bollinger, Bracken, Clark, Ferguson, Jaques, Noffke, Ronchi, Harris, et al.
Sure, Dave Hussey should have tests behind him, but he's played plenty of ODIs and is the first name on the team sheet in T20s. Katich played stacks of Tests for a 45 average, they just bumped him too soon. Concede Bollinger, they screwed him over. Bracken, Clark and Jaques were used well; its a shame Jacques was never the same after his back injury, but that's hardly the fault of the selectors. Ferguson hasn't had the form behind him to play Tests, and that's what we're building towards. Noffke was, by all accounts, a bit of a dick and a poor fit for the team. Ronchi was never good enough, and Ryan Harris has been our best quick in the last two years, but has been affected by injury. They've hardly been destroyed.
Johnson, Cowan, North, Smith, Hastings, Manou, Krezja, Bailey, Forrest, Beer, McDonald, Laughlin
Johnson was, for a time, the best bowler in the world (note, for a time. He should have been dropped far earlier than he was). Did England do the wrong thing by selecting Harmison? North and Forrest had Shield form behind them (FFS, hardly 'worshipping phantom potential' when Bailey, Forrest, Manou and Laughlin have one test between them), Hastings was one of our best performed bowlers, Krejza was the best option we had, given Hauritz was only playing grade at that stage, Casson lost the ability to bowl and the Cullen's weren't capable of taking grade wickets. Beer was uninspired, sure. Manou only played due to circumstance, Laughlin was tried in a meaningless ODI series and discarded. Cowan has the form behind him, and could well come good with an extended run; and McDonald was hardly the worst cricketer to represent his country. Oh yeah, and Smith still has potential. He's making runs at FC level, and could well become a good quality batsman in years to come (not necessarily Test first XI, but still..)
FFS, you act as if Hussey, Katich, Clark, Bollinger and Harris haven't played more than 5 tests apiece, while Manou, Krejza, Beer and Laughlin got selected for a decade without doing anything.
****ing dire posting.
EDIT: I can't believe I just defended Mitchell Johnson's existence...
