With the ABS system in place, having a catcher with an eye like Jeffers in invaluable. In my opinion, the discussion about framing is irrelevant. If a strike is called incorrectly, challenge it. Jeffers is doing extremely well at this. I also think that excessive glove movement by the catcher to frame a pitch might be making it more difficult for an umpire to make the correct call. The circumference of a catcher's mitt is roughly four times greater than the circumference of a baseball and hides the true path from the umpire. And the more that larger circumference move, the less of the ball is visible to the umpire.
