India had the chance to knock England out of the game on Day 1. If they had got them out for less than 150, they would have next to no chance of winning the game...unless India too collapsed in the 1st innings.
With 250, England still have a fighting chance, again depending on how well India bat in their first innings. It looks a good batting pitch. No demons. Just have to survive 20 overs of the new ball.
If India can get 400+, they could still be bossing the game. But 400 against 150 could have been game over....with 250, likelihood is India will still have to bat in the 2nd innings to force a win. Could have another Edgbaston on our hands.
