This raises an interesting question (at least I think it's interesting): is there any correlation between framing skill and ability to catch the knuckler, and if so, is it a positive or a negative correlation? I often read about how what sets great framers apart is how quiet their bodies are and how they can receive the ball with minimal apparent movement. And I also read that catching the knuckler requires a very flexible approach that doesn't commit prematurely to an expected trajectory for the ball. It occurs to me that these two requirements could be incompatible. Or it might be that both involve similar skills, just used differently. Anybody have any thoughts on this?
