I think, as an ex-opener, opening up is always the toughest place to bat. You’ve been in the field all day, 10 minutes to get sorted and then you face the new ball against in this case 3 top quality quicks bowling at express pace on intimidating pitches. No margin for error, one mistake, one moment of hesitation and you ‘fail’. The fact Cook has so many runs in that job shows his class but I bet if you plotted his runs per innings by innings he’d have a load of low scores, and a load of high scores and relatively few (for the number of innings) in the middle. Now he’s in, I’m hoping he can make a proper big score, although he also has the problem of starting from fresh again tomorrow.
Root on the other hand – great player, far more shots than Cook, but he gives it away for beautiful 60’s and 70’s far too often to be considered in Cook’s league as a run scorer for me.
