Our slip fielding has been egregiously bad. I can comfortably say we deserve to lose purely on the basis of that, and I see a heavy defeat forthcoming. We've rarely done well when faced with scoreboard pressure, and England will be doing everything they can to get even after the shitstorm of criticism that was unleashed at their team after the Lord's defeat.
Bowlers have tried, there's been some bad luck, and some bad lines being bowled, and obviously the lack of another frontline bowler has hurt us, but maybe this is the only way the Dhoni/Fletcher braintrust learns their lessons.
