To simply define an all-rounder would be a player who merits selection into his team for both their batting and bowling. Due to this role as a player who almost doubles their usefulness all-rounders have always been something of utmost interest to cricket. This includes the often criticized searches for all-rounders (see Australia/India in recent years) that inevitably occur to find players who could possibly fit such a role.
If you were to allow an all-rounder to qualify as a player with more than 500 runs and 50 wickets (Test matches) and averaged over 25 with the bat and under 35 in the ball you would discover that 40 of these players have existed.
Then if we breakdown where they have come from we can see which nations produce the most and least all-round cricketers.
New Zealand 5
South Africa 5
Sri Lanka 1
West Indies 2
Australia and England are far and away leaders in regards to alltime all-rounder production, yet they also have played Test cricket longer than any other nation. The lack of modern day all-rounders in Australia is particularly apparent when you limit the field to all-rounders who have played since 1970. Now only 17 qualify and Australia only adds a disappointing 1 to this number.
New Zealand 4
South Africa 3
Sri Lanka 1
West Indies 0
Of these players, six are current:
SM Pollock JH Kallis (SA), DL Vettori JDP Oram (NZ) A Flintoff (Eng) and IK Pathan (Ind)
So where have all the all-rounders gone?
