Mr T ... what Wellphyt didn't mention was what portion of the rear elbow lowering was governed by external rotation of the rear upper arm within the rear shoulder socket. This action is incredibly brief ... and actually leads to a resistive type fusion process. To make a long story short, only the first few inches of the rear elbow lowering process takes place while the rear upper arm is externally rotating. In fact, it is very important that all external rotation of the rear upper arm be quickly frozen out, basically fused, quickly during the rear elbow lowering. Failure to 'fuse' will lead to 'bat drag' .... that is, while ER often is present at the start of the rear elbow lowering process, it must be aborted relatively quickly.
From the perspective of the upper arm, there is actually a form of resistance that takes place to further lowering of the rear elbow shortly after the rear elbow begins lowering.
Here are the swing frames in Barry Bonds' swing in which his rear upper arm is externally rotating. After this portion in his swing there is no further external rotation of the rear upper arm.
Same goes for other high-end hitters. Here are the frames of external rotation of the rear upper arm for Cabrera's swing ... and again, there is no further ER of the rear upper arm after this point in his swing ....
Same goes for Pappi ....
Same goes for Pujols ....
In all of the above clips, ER of the rear upper arm is complete at the end of the swing clip portion shown ... there is no further ER of the rear upper arm ... yet the rear elbow has a long way to go in terms of lowering.
Experiment for you to run ... if you were to get your swing to the point at the end of the clips shown above, at which point ER of the rear upper arm is frozen/fused, AND if you were to begin supinating your rear forearm, then what would happen to your rear elbow? Mine would lower ... adduct.
