All I know is the ones who move big weight, 600-700 lb bench press, 800 plus squats look like shit. When dieted down, they look like shit too.

Really. ALL trainers who can move a lot of weight look like shit? Remember Ronnie Coleman?
Even bodybuilders who aren't considered strong: Jay Cutler, Phil Heath, Dexter... are in reality incredibly strong. Insanely strong. Maybe not by powerlifting standards or even bodybuilder standards, but by human being standards, gym rat standards, they are exceptional. Doing, say, ten reps ass to ankles squat with 315 is incredibly strong and puts you in the upper 10% of the population.
The fellow you posted is very, very strong for his weight but not physically impressive. But can you doubt that if you were to add 30 lbs of lean muscle to his frame he would not be even stronger? To say that there is no correlation between muscle size and muscle strength simply does not comport with common sense and real world experience. A marked increase in muscle mass leads also to an increase in strength and vice versa.
