Few modern-day international cricketers are as tall as Ishant Sharma. And few, as unpredictable. Ask him to bowl full-length deliveries. He can respond with full tosses. Or, give him an attacking field and ask him to go the short- pitched way, allowing the batsmen to hook or pull him. Instead of doing that, he can give friendly deliveries that the batsman who is eager to save the match can play with a dead bat. Slow. Easy.
