Also i see shot blocking as you
I make an example
Dwight Howard blocks 3 shots for game,but if i play inside against him,i always make more attention to his shot blocking,so i take worse shot than with another player and my percentage will be lower
So Howard it's a good defender,also if his have not the defensive tecnique of other defenders as Marcus Camby or Theo Ratliff
so shot blocking had to work as a multiplier of inside defence,if i have a poor defender,it have not so effect,as well as jump range,if i don't what to train shot blocking why of potential cup my choice is however right
we assume as shot blocking as a factor which multiplies inside defence
