I haven't got any idea why Katich has left out. He had proven his ability of scoring runs under pressure but I don't get the point of replacing him. Taking over him, Hughes has struggled thoughout the year, perhaps averaging under 30 which is actually low for any Test cricketer. If he would have scored some runs last test, he would have been in the squad for the India series. Cowan looks to be a good player, in my opinion because he's being in great touch and if he performs well in the warm game, I am sure that he will be picked for the test.
Well originally it was about his age, and making a transition from old to new. It wasn't because he couldn't play anymore. I think the selectors were just wary of having 3 over 35s in the batting lineup that wasn't really performing, so why not give a youngster or 2 a go? They also didn't want to get to 2012/13 and then all 3 players decide to retire just before the Ashes for example, so better to transition them out one at a time. Katich was the least valuable to Aussie cricket, so he got the short end.
Trouble is now that some of those young guys aren't going so well, fans want Katich back - it was always going to happen, but it's part of the renewing process I'm afraid. Personally, I think it's just short sighted and reactionary. It'll be the same people that call for Shane Warne to come back eg. after Lyon gets targetted around the MCG and Warney has a good game in the Big Bash...And as you say about Cowan, he might be just as useful as Katich, but 6-7 years younger.
I've got a problem with the type of players being selected and when they are selected rather than who's being snubbed. Picking players who go hard at the ball and then wondering why we keep getting skittled is stunning. Or picking players who aren't in form eg. Hughes last Ashes. Find us an opener who leaves the ball prudently and plays with soft hands and who is in form, and maybe some of these problems might start going away. Wouldn't go astray with some of our middle/lower order players too. It's a shame Paine's career is in jeopardy for example, he would have been a valuable fighter instead of having Haddin's airy wafts.
And yeah Justin Langer, he's dining out on his Test resume and the fact he can babble important sounding stuff. He's worse than Troy Cooley who we kept for about 2 years too long - the only bowler who improved under his watch was Nathan Hauritz...
