My mistake re: his total runs scored, in context though, it matters little.
It seems you're too pre-occupied with your own little fantasies about Hughes to realise that he quite simply ISN'T close to ODI selection, and neither should he be. He's barely averaging 30 this season, and at NO stage during his brief one day career, has he even past 70. You should also note in you inane ramblings, that Hughes has played the most innings, yet is only the 13th highest run scorer to date. The bloke is a star to be, but he's simply not ready for one day international cricket, and anyone with half a brain would realise it.
Marsh might have had 1 good season to day, but that really doesn't matter. What does matter though, is that he has played 8 matches for Australia, and has done whats asked of him (one could argue more, given he's averaging 47, since you're so hooked on averages). As I've mentioned, and as PEWS said, he's not being picked on form, but he's being retained because of what he has done.
If you don't like the Slater example, look at Michael Clarke. He was dropped from the test side, yet at the same time he was one of Australias top 3/4 ODI batsmen. There plenty of examples of FC form, not meaning OD form, which is why many people often disregard the opposing format when it comes to selection.
I called Howardj a joke, because he's prone to making ridiculous comments without ever backing them up. Marsh mightn't be as good a FC batsmen as Hughes is now, but at this stage he's done more in his OD career than Hughes has, and has actually represented Australia so to say he's "not fit to shine Hughes shoes" is rubbish. But hey, keep putting words in my mouth, and taking things completely out of context if you wish, it only makes you look a fool.
I don't know why I bothered replying, because it's quite obvious you've got little idea of what you're talking about, so this will be my last response on the matter.
