I believe you did misinterpret my words. Tendulkar, Dravid and Kaif did not gift their wickets away to Panesar--he was good enough to earn them under certain circumstances. These circumstances involved playing the new bowler with a lot of caution, perhaps even overcautiously. This is not a new fad with Indian batsmen, especially not Tendulkar. Tendulkar treats bowlers he has not faced before with a tremdendous amount of respect. Even with Botha debuted his off-spin in India, they did not take the attack to him.
Having got their bearings against Panesar, I feel they will play him much more positively in the next match. Panesar also took a very defensive approach (flat balls, for example) because he was playing his first game and did not want to give away runs. Hence he did not pick up as many wickets. From what I read on cricinfo, even the wickets he did get were ones that ripped, a rarity on the pitch they played on.
That said, Panesar will probably fetch a few more wickets if he gets the batsmen to play shots. All I'm trying to say is that although Panesar put in a decent performance, I don't think he put in an amazing one. As far as the future holds, he may well go on to become the most successful left-arm spinner. As for the present, he is probably eons better than Giles, and it was a positive move for England to draft him in. The Indians should probably try and mimick that move by bring Chawla in to the scene. However, I doubt we will take the risk of bowling two leg-spinners in tandem, even if one is double the age of the other! But if we do, it'll be great because Kumble will be able to offer valuable tips to Chawla, on-field.
