Wouldn't too much extensor action impede a player from swinging the left arm freely from it's socket?
I would not think so. You are only stretching the left arm via the right hand.
Stretch all you want but the joint structure will still be in place. The shoulder joint has no choice but to do its thing. What would impede the left arm is lack of extensor action - with lack of, the left arm would collapse - centainly discouraging a swinging left arm. Also, a non-inert left arm would certainly interfere with the natrual action of the left shoulder joint.
With extensor action the left arm is acted on.
Stretch the leash as much as possible (even if made out of a steel beam), if attached to a hinge, it will still swing, but with more structure, it will resist collapse, especially when something at its end hits another object (say for example, a golf ball).
When I wrote 'running in place' I only meant (trying to stay with the dog thing) that the pull was extreme and reckless.
A brand new rubber band is a circle- hold on part of it with two fingers (the left shoulder) and pull the other side (right arm) and it becomes two parallel lines- that is what extensor action is.
Could I have a tension in my left arm and shoulder?
You want your left arm to be as lifeless as piece of rope. The left arm changes conditions (to becoming taught, or straight) because of extensor action which is produced by action of the right hand. Left arm being or becoming straight is not a function of the left arm (rather a fuction of extensor action).

You can keep the left arm straight without extensor action-and I would not call it an action of the right hand-more right triceps .However I'm not splitting hairs -extensor action is important BUT some people already have it -and don't know it

Any pull (of the dog) has nothing to do with extensor action - a pull that is extreme suggests an active left arm (over acceleration) - not extensor action.
If you are referring to the pull as the stretch produced by the right hand - how can the stretch be too extreme? The hinge will direct the force. If your trying to hit a ball with any part of a lever that is a rope, you'd certainly want to stretch the rope as much as possible to provide structure, prevent collapse.
As for the rubber band, if the the assembly was attached to a hinge, you'd want an intense stretch just so hinge action could take place. (difference of force - cetrifugal or muscular, acting on a limp vs taught rubber band). With no stretch, hinge action would go awry. But this has no bearing on whether the stretch can be too much.
If indeed too much stretch can mess up the hinge or joint structure, I'd say you could have to much. But for all purposes, I don't think this is possible.
