The debate on whether Sunil Narine should open is one of my favourite in T20 cricket. I stand resolutely on team ‘yes’… but standing on team ‘yes’ does not mean that I don’t still have doubt. It wouldn’t be a debate if I didn’t see merit to arguments on both sides. I have built a simulator that will play out T20 games ball-by-ball, thousands of times, so that we can see the impact of playing in a certain way, or with a certain line-up. This means that we can set up a game between the Kolkata Knight Riders and the Sunrisers Hyderabad (say) and simulate what would happen with Narine at different spots in the line-up
