Are bowlers just flat out dumb?
Heard of a Yorker?
There is no harder skill to execute in the sport.
Miss a fraction short and you bowl a half volley that any even half proficient batsman can hit anywhere between mid off and fine leg depending on their position at the crease, miss a fraction full and that task becomes even easier. Bowling short of a length you’ve got a two meter area to hit. Bowl short and you’ve got an even bigger area to hit.
There is a reason literally EVERY bowler on the planet knows WHERE to bowl in the last 10 overs of an ODI but only a dozen or so can actually be trusted to do it. It’s because actioning a plan isn’t as simple as just saying ‘yeah that’s where I want to put it.’
