Lenski is just stubborn and doesn't care to consider facts or opinions that contradict with his own beliefs. 2 simple examples - 1) he believes that catchers see and visually track foul pops from the instant of contact just like any other fielder; 2) he believes that his DD doesn't pull pitches.
FWIW, I am one who considers NECC's instruction as gospel. But I arrived at this point after considering my own catching experience, reading and viewing everything I could get my hands on or was recommended to me, personally trying alternative techniques, and experimenting w my DD and the other catchers I coached. Having gone through this verification process, I trust NECC and have no reservations recommending their approach to anyone.
Trust, but verify!
Let's talk about stubbornness and considering facts and opinions. I'm the one that said if a catcher wants to keep their mask on it is fine. I never said it was wrong. I call it a preference. You're the one that is adamant about keeping the mask on. I am not the stubborn one here, you are. Yes, a catcher is more aware of their surroundings removing the mask on a high pop up. That's why the best catchers do it. If you don't want to believe that little tidbit of information, it's not my problem.
A good catcher sees the direction of the ball from contact. I said that since they know the direction they can find the ball very quickly, within hundredths of a second.
You need to understand the difference between a push and a pull, and the smoothness that the task is accomplished.
GM, since you consider NECC instruction as gospel, let's see your NECC instructed dd catcher in action. Throw some video on here and compare how my non-NECC instructed catcher compares to yours, with commentary on what my dd is doing wrong and how she should fix the problem. Maybe you can teach me something.
