I was surprised there was ever a discussion on hots streaks? Or did I misread that part. Averages are what they are, averages over a longer time frame, year career etc. Streaks are in essence SSS, and have existed forever. As to clutch hitting I have long been a believer that clutch hitters are somewhat of an illusion. How so? I think that most of them simply perform to their overall career stats, in important situations. Basically not letting the magnitude of the event over stress them, and letting themselves "slow down", so as not to over react and do something they can't. For if simply trying harder would be enough to give you better results, then everyone would do it, and do it in every game, as trying is simply effort compounded. As to pitch framing. My neighbor and long time friend was a D2 caliber catcher. He caught for years in men's amateur ball, and then umpired for something like 26 years to levels in the state tournament range. Men's, high school and Legion. Ho told me years ago how he showed pitches to an umpire by glove postion, and lack of glove movement, and not being greedy on the ones you can't save. And he said that the same applied to an umpire. A catchers low stance, and how he sets up and receives matter, a lot. While it took stats to more widely make the concept acceptable, cathers and umpires have known it for years, although I doubt most umpires are willing to admit it.
