Interesting question and even more interesting responses. We have had our share of very good catchers. Each has their own camp pop times and each has had improvements - regressions over the years. I had this discussion last month with a current D1 HC that happens to be married to a former D1 catcher. He said he, and many of his collegues, pay little attention to pop times captured at camps like NFCA and school clinics. He said while those do show arm strength and basic foot skills they only tell a portion of the catchers throwing ability. His assessment is that when a catcher is in game situations, catching varying pitches in different locations, and determining if the runner is leaving or not is the real determining factor in her real pop time. He said they never downplay controlled pop times - but they don't recruit catchers based on controlled pop times either. The only way they do is to watch and time catchers in game situations. Which most caches do.
A perfect example of that is that the catcher of ours that he is recruiting has our second fastest controlled pop time. But she is far better/faster in the above mentioned OTHERS. Her true, game pop time is what got his attention.
