LOL implying Rippetoe's advice holds for anyone past the first 4 months of their training. I've seen Elite level lifters progress faster on Westside or Bulgarian Method than most novices on SS/SL/TM/MC, etc.
And I'd say what Ed Coan did is more effective than SS. SS simply is not enough volume nor intensity past the most beginning stages.
The kid could go to a competition right now and place well with a squat well over 2x bodyweight. I don't know how many of you Rippetoe nuthugging tough guys or even Rip himself could do that.
Programming can still be very simple, but there's no need to follow a strict template. Just make sure your form is as perfect as possible, do multiple sets of 1-5 reps multiple times a week, throw in whatever assistance you need, and you will progress even well past the Elite level.
