Can two cricketers be compared?

You must have seen or heard people saying
Don Bradman is the best cricketer,Sachin
is the best cricketer,Lara is the best
cricketer and blah blah.These are the people
who have seen anywhere an average of that
batsman or no. of centuries he owns

It is very much crucial to compare two cricketers
because they plays in different pressure,different
style and different crowd.With what pressure Sachin
have played and performed well cannot be same for
other cricketers.Sachin bears the psychological
pressure of performing well while playing cricket.
We cannot surely say that if Don Bradmen were play
for India then he would have registered the average
of 99.94 than also.

One time Sachin Tendulkar's childhood friend
i.e. Vinod Kambli was said to have more talent than
him but what matters for us is the final result we
currently have.If Vinod Kambli would have got proper
environment for cricket then surely his final record
were better than the present.

Anytime a cricketer starts playing well consistently
we start opening our mouth for doing comparisons between
him and some great cricketers.

New Zealand's former Cricketer Richard Hadlee said that
Sachin is best because he have good record in both
Test and One Day.Sir Donald Bradman did not play One
day and Hadlee compared Sachin with Bradman on the basis
of his good performance in One day.But what if Bradman
would also have played One day and performed well.

Sir Donald Bradman played 53 Tests and made 29
centuries.When Sunil Gavaskar 'broke' the record
of 29 centuries everybody start congratulating
him but he said Sir Donald Bradman's 29 centuries
record will be said to broken if anyone would make
30 centuries after playing equal to or less than 53
test matches.

So a batsman can only be differentiated based on
his particular record.Comparing a batsman will
also be very much contradictory when any old
cricketer says it any press conference or in any
column in Newspaper.
