No doubt he would bench a lot more, but an 800 raw squat? Those arent that common. I think a lot of people just believe it isn't possible to train squat that often, but olympic weightlifters have been putting up insane raw squats for decades, and they don't even train to squat competitively. of course it's going to be ill-suited to equipped meets in PL, but I really think people just dismiss it without understanding it or giving it a really fair chance with a good coach (not saying that of you individually of course!).
I do certainly understand the idea that people don't have 12 workouts a week to give to the gym. That is certainly valid, and people have been getting strong on Westside and other methods as well. But I personally would not dismiss it as ill-suited to raw powerlifting off hand.
EDIT--i seem to have wandered off your response. Yes, I think he undoubtedly would bench significantly more!
