I think I know something about cricket - and so I tell others they have no idea
I think anyone who has read the exchange will realise that there's one person with no idea - and it isn't me.
Unfortunately you're pushing a fully loaded wagon up a hill and screaming out that it's not heavy. Clearly it is, and you're struggling.
If you want to make absurd comments about Marsh having a better OD career (at domestic level than Hughes then you're got the weight of evidence on your back to prove it. Marsh is at 33 on the domestic scene, Hughes 36 - and, as you correctly point out, Hughes is still to hit top gear in the OD scene.
I would have thought it was reasonably common knowledge that Marsh got picked for Australia based on his T20 form both last summer and in India? It had nothing to do with his domestic OD career (which is solid but unspectacular). And being the 'incumbent' batsman with an average of 47 is a tad misleading - he got a guernsey against the Windies (being the backup opener on tour - taken because he was seen as a 'potential opener of the future, thanks in large part to his strong summer last year [[which has turned out to be the exception and not the rule]]). - and averaged 30 against them. Found himself playing Bangladesh the next month and tonked them everywhere. But then so did Jason Gillespie.
Incumbents who play a few matches have been dropped plenty of times - especially when the incumbent is sorely out of form.
I'm not advocating picking Hughes because he's the best Ford Ranger batsman in the competition, I'm saying pick him because there's a career for him as an Australian opening batsman in ALL formats of the game AND he can field in the slips. Goodbye Hayden, hello Hughes.
Marsh got picked on IPL form to play ODIs --> why not pick Hughes on sheer form in ALL facets of the domestic game to play the ODIs (as a precursor to moving him into the test team on the upcoming tours...)
Heck - if I were going for the "most in form" batsman in the domestic OD scene it'd be someone like Warner (who they selected for the T20s but not the ODIs?? Odd considering he's been fantastic in the One dayers but only had one good innings in the T20s...)
