Bowlers wins Test matches.
I believe having 5 proper batsmen including Don Bradman and Adam Gilchrist is enough.
Four ATG pacers(Marshall, McGrath, Hadlee, Imran) and Murali is enough to dismiss any opposition for me
Shortening spells to accommodate more bowlers delivers significantly diminishing returns. Definely not worth playing a batsman short and for another reason.
And speaking of said reason, how and where did McGrath and Hadlee taken the vast majority of their wickets? Where did Marshall take about half of his?
The keeper and slip cordon. How many specialist, far less great slip fielders are in your team? One.
You stick a team full of fast bowlers who took most of their scalps caught behind the wicket, all had peerless cordons (most of us can easily name the gentleman than made up each) and then give them none here. Guys like Lillee, Lindwall, the WI battery, McGrath, Steyn, Hadlee etc relied and depended on the brilliance of their cordons. Simpson was even drafted into the Aussie team because too many catches were going down and they needed the support to get the best out of their 3 greats.
Let's go even further. What has been one of the main determinators for success in this ongoing series? When Australia held their catches, they win. When Khawaja dropped Jaiswal, and when Smith dropped K.L, they lost or drew the matches.
The two catches held by Smith in the last contest were not only brilliant (Khawaja isn't catching either), but in such a closely contested match, both were critical.
So yeah, short batting (6 is a spot too high for Gilly at this level), long tail, and outside of Sobers (and Hadlee at gully when not bowling, and even then..), no catching support. There's a reason Warne is a much more popular choice in these exercises, he wasn't great, but he's useable (though arguably not at this level) at 1, and can bat, while being every bit equally as good with the ball. Richards, while being the best ever batter vs pace, was nothing short of brilliant at 3rd slip, and everywhere else in the outfield for that matter.
So while you're stacking the attack, you're not giving them the support they would require.
