It’s not that the England fielders lack the skills to take world class catches, it’s that they lack the confidence to do so when under international pressure

It's not exactly iHawk(!) but this shows nothing's ever quite as cut-&-dried as it looks (although it still looks doubtful...). The biggest problem is from this angle you can't actually see where the ball pitches or where it hits the pad as the umpire is in the way

If the wobble seam is doing this much then why try to swing it? Swing is harder for a bowler to control but seam is harder for a batter to play
