On hindsight, India could have won the Natwest series 7-0, but should have lost it 7-0. Let's take them one by one.
1. At the Rose Bowl, teams batting first in day-night matches have usually won, because the pitch freshens up at night and makes the ball zip. Dravid chose to field first, probably going by his experiences in India where the dew gets so heavy in winter day-nighters that the ball gets wet and loses all movement. This decision cost India the match.
2. At the next day-nighter in Bristol, Dravid chose to bat first, thus acknowledging his regret at choosing to field first in similar circumstances in the previous match. India was lucky none of the batsmen failed, except Karthick, because it went in with a batsman short as Dravid wanted to play two spinners and also retain all his three seamers. The fifth bowler made little difference as England came within nine runs of India's mammoth 330.
3. At Edgbaston, Dravid went back to fielding first because it was a day game, and he remembered the early help his bowlers got in the matches against South Africa in Ireland before the Test series. But he failed to take into account the record at Edgbaston where teams batting second have lost because the pitch slows down, making shot-making difficult. To compound matters, India was still one batsman short, which meant Yuvraj ran out of partners even though the asking rate was well within grasp.
4. In Manchester, Dravid switched back to batting first, but this time encountered typical English conditions and got bowled out for 212, the batting lineup paying a heavy price for carrying five specialist bowlers. England got into trouble too, losing seven wickets for 114, but India could not finish the job, underlining the futility of playing the fifth specialist bowler.
5. At Headingley, Collingwood chose to bowl first, going by Headingley's record of favouring bowlers early on. It was a sunny day, however, and India piled up 324 in balmy batting conditions, with Dravid having finally switched back to playing six batsmen plus keeper. It started drizzling when England batted, and when Duckworth-Lewis entered the equation it put the final nail in England's coffin.
6. At the Oval, Collingwood switched back to batting first, and piled up 316 thanks to Dravid's largesse of handing Yuvraj the ball for the last over in spite of his most economic bowler Ramesh Powar not having completed his quota. Finally, the sixth batsman Robin Uthappa's heroics in the last two overs saved Dravid the blushes.
7. At Lord's in the World Cup final of 1999 Wasim Akram discovered why you should field first when in doubt. Dravid probably stung by all the flak he caught for choosing to field first at Edgbaston, went against his inclination and chose to bat first. The pace, bounce and movement sorted out the Indian batsmen who were all at sea. The margin of loss was so huge that I don't think Aleem Dar's error in giving Tendulkar out was the decisive factor, even though that's what Dravid was happy to draw attemtion to after losing a series with bad captaincy.
In sum, Dravid lost the first and last ODIs after taking wrong decisions after winning the toss, and lost the third and fourth ODIs by playing five specialist bowlers. For India's sake, he should chuck the captaincy. We can no longer keep finding excuses for India's flop show in one-day cricket before, during and after the World Cup. We need an astute captain and coach, better selection and competent administration.
