I am sorry - but you made the claim that Blake had a better playoffs than Hinrich did - so looking at their numbers and comparing them, defensively, against who they went against - makes sense when assessing this statement.
The numbers show us that Kirk had a better PER (mostly, better offense) and a better DWS (measuring defense). When we actually look and see who they faced - the comparison between Brooks and Rondo makes sense.
It's all about context... In the context of your argument - this comparison makes sense. I am not the one that made the declaration that Blake had better playoffs than Hinrich - you did - and this statement is just plain wrong from a simple statistical evidence. It is even more damning - on the defensive side, when you consider their opponents.
Does this make it clear why I made the comparison?
