1. There was nothing in that post to agree with, there wasn't a single paragraph of the three that made any coherent sense, so if that changed your mind, you wanted to change it.
2. Easier to find doesn't mean less important. I'll also dispute easier to find, because there's a paucity of world class slip fielders in the world today and even some of the better ones as referenced by
@HeathDavisSpeed , or a Khawaja has inopportune drops that costs matches. I would also argue on the value and you should ask McGrath or Warne about the value of Waugh or Ponting and 2nd.
3. What constitutes a good no. 8? I would say Cummins and above. Let's even raise his average to a hypothetical 24, that's worth more than having all of your catches taken? I would argue no.
4. Kallis and Pollock played together for a considerable period of time . Between Kallis's catches at 2nd, and Pollock's lower order runs, which contributed to more victories. Kallis was invaluable to SA and to guys like Steyn. It was edged, it was caught.
5. I would love you to name the great teams in history that were build around or elevated by lower order batting. Batting depth is always appreciated, and guys like Marshall / Warne / Cummins etc more than easily fill such roles, and none .....
6. We're more important than the slip cordons their teams had. I've asked you this countless times. Given the choice, would Australia / West Indies / South Africa have traded out the quality of their slip cordons for even Imran level batting depth at 8.
It's a simple question and a very simple answer.
And the nonsense with regards to the marginal value isn't so marginal when Usman drops a batsman that goes on to score a double hundred and you lose the match.
I'll maintain that all 3 are very important in this game of cricket, and if you have a weak team with not great specialists, that amplifies the need for all 3 even more.
But if you want to be elite, there's only one that a team can't succeed without.
