I can understand that. I made a mistake. I should have taken an off spinning all rounder in place of Mankad. Now with Sobers already available people tend to consider Mankad dispensable. Unfortunately great off spinner all rounders haven't been many and I did not want to put someone like Jackson since many people are not very familiar with him.
My idea was for the bowling attack to have everything. A pacer who brings the ball in (Imran), another who can take it out (Miller), a left arm pacer (Sobers, a left hand spinner (Mankad) and a leg spinner (Benaud). Hammond fills in as a right hand medium pacer. He was of course a much better bowler than people are aware of.
That would give a complete attack and people, if they wanted to maintain the variety in attack would have to replace like with like as one poster has done by replacing Benaud with O;reilly
