Well, the mythic golfer is talented, but he's not super human. He doesn't attack the golf course at will, he executes the shots that the course design dictates. At the 16th at Augusta on Sunday, he'd aim at the pin and hit a cut. The cut would land 10 feet right and just short of the hole, rolling down to within 3 feet.
The mythic golfer is the guy who writes the yardage guides you buy in the clubhouse. Hit a draw down the left side to avoid the buker, hit a cut into the green because there's a backstop back right - bingo, bango, bongo. It sounds so easy.
I aspire to play like the mythic golfer, though my 17 handicap only lets me do that on 1-2 shots per round. The rest of the time, I am cursing the mythic golfer from the bunker.
To bring it back to your original post, Tiger's play at some times can teach us something about architecture. Like Memorial this year, with its long rough and short-ish approach shots. Tiger hit lots of 3-woods in the fairway and his approach shots were sublime. In the majors this year, he's had bad breaks (weather) or just played poorly. When I played Bethpage 4 years ago, I was struck by how flat and puttable the greens are, yet Tiger putts terribly this year? That's not the architecture influencing his game, that's him putting terribly.
