"Fact is proper scap loading technique/time wise is a must to protect the entire shoulder."
Why exactly is this? Why don't you think the body can take care of this itself?
"There opinion of scap loading is jamming the elbows behind the acromial line or a "hyperflexion" action which is not good. They dont know how/when its supposed to be done therefore they automatically think its wrong."
So exactly what is it and when should it be done? What purpose does it solve?
"Scapular dynamics are always affected when a player has an injury."
I assume you are talking about shoulder injuries. Of course, this is a given since the scapula is the key structure when it comes to the shoulder joint.
"Chris a person does not load the scap with his elbows down, this would produce way to much friction upon elevation."
So then how do you explain what Nolan Ryan is doing in frame 27.1 (among others) of this document...

"Proper scap loading has nothing to do with rotation of the humerus either."
How could it not, given that the purpose of the muscles that attach to the scapula is to hold the proximal head of humerus in the socket and articulate the humerus (e.g. upper arm).
"Proper scapula dynamics serve to provide a stable base as well as funnel the energy to the throwing arm instead of wasting it elsewhere."
I agree, but I'm not convinced that this is something that the body can't take care of naturally.
"Most successful pitchers do not get the arm up nearly as quick as Marshall likes to see his pitchers. Which is one reason why they will never amount to much in my opinion."
But some like Freddy Garcia do. So you have a low opinion of him?
