The Zinger never had his left elbow facing his body and he did alright.
Hmm... I kind of thought that the left elbow position was pretty much dictated by the type of grip. Both Azinger and Couples have strong left hand grips which makes me think it makes the elbow point more toward the target. Weak left hand tends to have elbow pointed more at the hips. Yes? No?
Of course, you can always manipulate the elbow position no matter what the grip type, but my own experimentation shows this does not yield consistent results.
