I’ve formulated a progression/introduction series that has been in place since 2007.
It’s more holistic, versus rigid, in terms of which drills and how much.
In short, my suggestion to you is to take the drills that are closest to what you already have your athletes performing, in addition to those which you know they can safely perform, and graduate their introduction in terms of volume and intensity.
They are placed at an auxiliary capacity in my programming and I should note that many of them are appropriate for nearly all American football playing positions due to the structural shoulder traumas that are common amongst everyone on the field except kickers/punters.
The key is to regulate the performance of the drills that require/generate more than needed mobility about the shoulder.
It is nearly as contraindicated to develop hyper mobility in non-throwing positions (for protection reasons) than it is indicated for throwing athletes to develop the necessary mobility for obvious reasons.
