Yes, he did. He believed turning your feet out screwed up the gait cycle.I remember Kennith Jay had strong opinions on this as well.
It was actually quite the opposite: I point my feet straight ahead because I'd torn the labrum in both my hips and this keeps me asymptomatic, and more stable. Furthermore, my kneecaps naturally track laterally (shallow trochlear groove, lateral sides), so pointing them out irritates my IT bands and my knees in general.I also seem to remember @Geoff Neupert referring to his feet straight forward stance as something to do with his hips being awesomely strong/ advanced technique from Oly lifting/ something along those lines and most people shouldn't do it. I think it was in one of the kettlebell burn extreme "watch me workout" videos.
I used to point my feet out to about between 15 and 30 degrees, and my right one would always externally rotate more throughout the set.
