Player Performances

I want to follow Aristocrat and make an unbiased study of performance of Du Preez and Steyn over the past three years.    Can anyone suggest a website from which I can download Tri-Nations tests during that period. 

You will find it very difficult to find anything from 2010 and further back. There once was a place called Diawana, that no longer exists.

What exactly to propose we study? I have a full compliment of match footage and statistics for all of the last three seasons.
