I was just having a discussion with someone about what is important to catcher defense and that was brought up by the other party. My question to him was "does the umpire ever even look at the catchers glove after the ball has crossed home plate"?

The strikezone isn't defined by where the catcher catches the ball, because the catchers glove is well behind home plate. The strikezone is defined by where the ball is when it crosses the plate.

So, I bring it here to you guys.... how much, if any importance do you actually put on a catchers ability to "frame a pitch"?
