My object is to measure the value of middle blockers. Traditionally, blocking prowess is measured by number of blocks and block touches, while attacking prowess is measured by attack percentage. Simple.
But my feeling is that does not necessarily tell the whole story. I feel that the overall effect of the middle can be better measured by using some version of sideout and break point percentages. My reasoning is that as well as the raw points that player wins, the team percentages can also at least implicitly measure how opposing teams adjust their tactics to reflect the players they are faced with. Of course, this number includes a lot of noise (surrounding players, defence, transition attack etc etc etc). So this is my question.
What are the pros and cons of using a team number to measure the effectiveness of an individual player?
