[quote=“Roger”]If a pitcher pulls his glove back, there’s a good chance he’ll rotate the shoulders early.
If he flies open with his glove, there’s also a good chance he’ll rotate early.
If he drops his glove, there’s a chance he may shift his posture and/or rotate early. So, there’s a list of things NOT to do.[/quote]I’m with ya. Well stated.
[quote=“NPA guy”]…that to do otherwise is to mess up[/quote]I’m assuming he means to not do eq & oppo is to mess up. Am I reading that correctly? If so, this is where I have difficulty. Roger, you and I have discussed this privately many times and you once, at least, mentioned that it’s the upper arms and the angles to the lower arms that are important in e & o, not the absolute positioning. IOW, the forearm could be pointing downward more or less on the glove side and upward more or less on the throwing side but, if the angles are equal, then you satisfy the e & o parameter.
Again, my problem is that, if you look at those clips that la showed, you see Verlander with the glove side arm very much tucked in while the throwing side is not. Randy Johnson’s different again. The throwing side is bent to approx. 90 deg. at foot plant (ubiquitous) but the throwing side is very straight. He’s a “sweeper” with respect to the glove side. So, I don’t see e & o re: angles when speaking of the forearms.
Like I said earlier, there’s a lot of activity happening on the throwing side with less on the glove side.
If we now look at the scap loading idea, this is where I do agree with e & o. Also, I propose that this, at least, is tangible for the developing pitcher. The positioning of the elbows and shoulders in a dynamic activity is graspable.
So, you ask “what should you do”? Work on the timing elements of getting to a good position at landing, whatever you believe that should be. There’s much variation on how to get there and through it to release. Moving the front hip sideways toward the target with as much momentum as you feel you can control WHILE the throwing arm moves as you see fit toward and through a “high cocked” zone WHILE the elbows are moving is similar fashions a la “equal & opposite” within the scap loading scenario that you believe is appropriate. Some like to focus on hip/shoulder separation into landing as well. Not rotating the shoulders before landing. Adding equal angles of the forearms and I think kids’ heads will explode in the attempt.
