A. well obviously,anybody who is watchin cricket for a long time will tell that it was change of his attitude in agression.it became sort of controlled agression.but main reason was tennis elbow and back injury,bcos of which he has to cut down his range of shots.so sachin had no choice but to restrict his movements and cut down shots to prolong his cricket career which he eventually managed.i dont think there was any case of sharing responsibilty cos then also there was dravid,laxman,ganguly who were experienced enough and everyone knows sachin,s best form of defence was attack but unfortunately it was dur to injuries he had to change his game.
