A
Anthrax Invasion

I know that squatting can be done in a variety of ways. Rippetoe teaches it as a generic power squat, pretty wide-stanced, bar low on the back, forward lean.
The thing is, the more forward one leans, the greater shearing force is placed on the vertabrae. Would squatting with a closer stance, staying more upright, be better in terms of spinal safety, then? I have three bulging discs in L3-L4, L4-L5, and L5-S1 now. I want to avoid a recurring injury once I begin training again.
Arioch said the following:
"At only 90 degrees of knee flexion, the sacrum is still tilted backward, which inhibits proper firing of the erectors and gluteus maximus and minimus. Going through a full range of motion completes the rotation of the sacrum and allows maximal muscular recruitment."

When I sink really deep on squats (I'm 5'11.5", have easily broken parallel since I started squatting - it came natural to me) I feel as if my lower back is "tucking under". Is this just the rotation of the sacrum he's speaking of? Or is any sort've shifting around the tailbone/lower back a bad thing when squatting?
