Framing has been around since the 70’s, at least in my experience as a catcher back then. I think those that believe umps are influenced by it, are over reacting.
The K zone we see on tv broadcasts, seems suspect to me as to what the real zone is, and actually would serve a better purpose if some IT guys could use historical data from each ump’s zone calls and plug that into each broadcast?
Also, since base stealing seems to be completely forgotten about (one more reason today’s game is not as good as it once was) is a catcher’s arm really something to worry about?
