Depends on the nature of said attrition. McGrath-like outside off-stump attrition = good Test cricket. What we saw yesterday = "Hmmmm.......what's on the other channel?" The difference between the two in the respective skill involved in both. Bowling like McGrath takes a lot of skill. Bowling a foot outside leg-stump to a guy looking to hit you around knowing he'll sky one eventually requires much less skill.
Bearing in mind, I'm in no way advocating that India shouldn't have done it or that it should be sanctioned because it's part of the game and at that level, I'd prefer the team to win than be nice. But it was quite dull to watch and I didn't find it a celebration of the skills of either side.
By your logic, Aus have been stupid for years for batting quickly and wrapping up Tests in 3 days when they could have played far less risky cricket and still won easily. I know what I prefer to watch.
I think you're selectively speaking then. If you take India's tour to Australia in 1999-2000, in one of those matches, India were something like 26-1 in 25 overs. Why? Same line by the same McGrath and Gillespie (IIRC), outside off stump line, which the Indians didnt even go anywhere near. Nobody blamed McG then for slowing things down to sleep. Good cricket? For me yes, same as now at Nagpur.
And didnt Johnson use the same line against Tendulkar & Co? He got Tendulkar chasing a wide one in the first test. But after that he was wary and was leaving outside off stump, and Johnson had "immaculate" figures of 10 overs 18 runs. Nobody regarded that as negative,
Zaheer and Ishant bowled only about 1.5 hours of outside off stump line, and Katich and Hayden chose to leave everything, even those which were periliously close to off stump. And once that became the norm, Indians started to attack the stumps regularly, and got them all out.
Further, spinners adopting negative line is a joke, because Bowden was signalling wide at the first instance of Sehwag bowling one outside leg. And if you note, Bhajji was bowling around the stumps at Hayden into the rough. Is that negative?
