I think not.
I think this claim and/or marketing hype may just be the thing squats needed: A return to true strength training...
Death of the Back Squat?!
ROFTL with the RFESS

The Disappearance of the Posterior Chain
Also, in the case of working with beginners, I can't think of a better, even possibly safer, way to develop and teach the intense volitional effort needed to build true strength (and, I truly believe, that high volitional effort is a rare trait these days). Teach and demand great technique...
And... one more thing... let's not make the weightroom more necessary than needed by spending all our time doing endless amounts of lifts that barely challenge the 'whole' organsim. Let's kill as many birds as possible with a few stones, and get out of the weightroom and work more on the necessary sports and movement skills.
A note: I think Coach Mike Boyle is a brilliant coach, I just disagree with his No More Squats, and I think it is important for those that disagree to voice their opinion, as he did his.
