For me, he has redefined how an opening batsman can approach an innings. His performances in this recent series have been quite phenomenal, we helped him at Mohali by dropping him early on, but then that is the game, and it is not Sehwag's fault if the opposition would not accept chances.
He is effortless, with sublime timing, he is destructive, often able to score over 10 in an over, he puts the bowlers under severe pressure often until they crack. He hits sixes as though the ground is only the size of a postage stamp. He gave us grey hairs trying to find ways to dismiss him!
I would often sit in front of the computer with Sehwag's innings on the biomechanics screen searching for the weakness, looking for the line and the length that would give him most difficulty.
In the end we settled for a short ball targeted into his chest, while this stunted his run scoring we did not get him out this way.
Early on in his innings his strength is his weakness, the short ball swinging away but on a tight line to the off stump might induce a nick to the slip cordon, if he tries to hit it harder it often flies over the slip cordon or if you are lucky he drags the ball off the inside edge onto the stumps. They are not conclusive ways of bowling to him, however.
We were able to run him out occasionally and at times he gets careless, we did not see much of that in this series unfortunately.
What makes him so good? He follows the most important basic principle of batting; he is still when the ball is released and is therefore able to judge length early and then make the shot timorously without flaw. His balance when he hits the ball is a joy for any coach to study as he transfers his weight perfectly, makes contact with an ability to hit the ball extremely hard but look as though he is just caressing it. It is the wonderful gift of timing, pure timing, that makes him so dangerous.
When I watch him he seems to have no regard for a bowler, it is the presence of a man who does not believe he can get out. Viv Richards had it, Graeme Pollock had it and Barry Richards had it and Adam Gilchrist has it. While unique in appearance (every individual is different) the result is the same.
Yet despite all the above Sehwag's results in the limited overs matches are significantly poorer than his Test match record. The white ball is not his favourite; he plays differently as though he is a loose cannon, his discipline that he shows in the multi-day game seems to go out of the window and it looks as though he is in a competition to see how far and how often he can hit a boundary.
While he is still very dangerous he gives the bowler more chances, I guess that is also the nature of the game. It is interesting why though he cannot just bat normally for 45 of the 50 overs as he is such a good player that he would still ensure a big score.
If I were to have a criticism of the Tendulkar-Sehwag partnership neither seems prepared to go the distance and both want to outscore each other!
His off spin bowling is totally under-utilised and it staggers me that he does not bowl more. He is excellent in the field takes catches in the deep and close with relative ease. He is a very complete cricketer.
His batting definitely takes on the qualities of a genius, like Bradman used to he is able to dominate attacks and will do so all the while that he is prepared to be hungry at the crease.
I cannot imagine a better technique and he could perhaps play the short ball better, but there have been a lot of batsman who have played the same way, hooking too early can lead to dismissal and stern and angry looks from coach, captain and team-mates.
He is so confident in his ability that he was quoted as saying that if he had not been run out he would have won the game for India at Bangalore, we shall never know if that would have been the case. He was certainly a threat and Inzamam delayed his declaration because of that threat.
In conclusion, India have unearthed a jewel, amazingly he learnt his cricket as a middle order batsman but has taken to opening like a duck to water, his technique is one to copy his propensity to go on and on after scoring a hundred makes him a modern day great. However and most remarkably it is his sublime timing that for me makes him a genius.
