Reverse Shrugs

I read in an Eric Cressey article that shrugs are bad. I think he said it was because it causes a vertical rotation of the scapula or something. I was wondering if reverse shrugs would have the opposite effect and help in shoulder stabilization. I cannot find any articles on this.

Here is a video showing what I mean by reverse shrugs

I call those Serratus Dips or Dip Shrugs. They are a great preventative based exercise and recruit the serratus anterior and other scapular stabilizers. I would not put them in the same category as the traditional shrug.

i thought the only issue with shrugs was rolling the shoulders
