Think it threw a little further,
(sharing this thought process)
Is there any reason the rest of the defense should kick back just cuz theres no one on base?
Is there any reason the pitcher should have a different looking target to throw to?
How about the umpire?
Would it be advantageous to have consistancy framing?
I'm not saying that they're kicked back without runners on base. If anything all your doing is convincing me to get into a secondary position on every pitch. Maybe our catchers are too low in their stance in general and that is something we can work on.
