I think the shot type stats should dictate how well you can play swinging/seaming deliveries or even just good/perfect balls. For instance if the AI is bowling good/perfect the balls outside off and you are continually trying to cover drive it maybe the shot type slider could directly describe your chance of middling the ball, so if say Steve smith has 98 drive ability, he has a 98% chance of middling it where as a jimmy Anderson with 7 drive ability has a 7% chance of middling it. If you don't get the percentage swing then you edge it or play and miss
