It seems pretty specious to make a blanket judgment - must less indictment - of a golf course based on what the winner shot in relation to par.
Have a scorching June, the usual dry winter, slow the fairways down, slow the greens down a foot and bring in more slopes, add half an inch to the rough, tuck more pins, all these things could substantially change the winning score and would have nothing to do with the golf course as it sits there.
