Hi John
Throwing a ball is a very informative tool to use for the backcast. Get the student to throw it back over the shoulder and you'll soon identify whether any medical related physical constraints pertinent to all the muscles that comprise the shoulder, and very specifically the rotator cuff group.
I always ask about pre-existing conditions before we start, you know if you have issues in this area.
When the use of a rod and line complicates the learning progression
What behaviour do you typically see that complicates learning progression that is cured by use of the ball catcher?
It would be great if that statement was correct.
It’s straight from Huber

Both good outcomes and bad outcomes are associated with the autonomous stage. The good is that performance requires much less attentional and cognitive demand, which thereby frees the performer to engage in secondary tasks, such as the concert pianist who is able to follow random digits or perform arithmetic while simultaneously playing the piano (Shaffer, 1980), or the quarterback who is capable of surveying the defense and detecting an eminent blitz while simultaneously calling the signals and changing the play at the line of scrimmage.
The bad is that since less cognitive demand exists during performance, it leaves ample room for irrelevant and distracting thoughts to sneak into the workshop (working memory) of the mind. Examples of this occurrence are the elite athletes at the Olympic trials who get caught thinking about making the Olympic team instead of focusing exclusively on performance during the last moments of a gymnastics routine, swimming race, or wrestling match.
We’ve beaten this topic to death, I’m just going to leave a summary of where the science is at:

In most circumstances studied, external coaching cues appear to be more effective than both internal and normal cues for performance, skill development and retention.
