Since his debut he has been one of the best test batsman in world cricket. I have him in tier 1 along with Tendulkar, Lara, Ponting, Kallis and Sangakkara. Of those he was the best at playing the moving ball, and probably was India's best batsman of the 2000s.
He should be remembered as a player who had a superb defensive technique and extremely good powers of concentration and mental strength, but also as a player with all the shots in the book, and one who could stylishly take apart bowling attacks when he occasionally wanted to. He was clinical at putting away the bad ball, and I think his strokeplay and elegance is and was sometimes forgotten in his overall reputation.
An all-time great player, a great team man, an adaptable player and someone India could count on time and time again, responsible for their greatest achievements.
