I'm not sure how putting a caddy's name on a trophy is relevant.
That said, yes, those are important skills. So is making a sound swing. So is making a good putt. So is performing under pressure. Sorry for the bad analogies, but I feel you're just drawing an arbitrary line and saying anything beyond it should be the sole responsibility of the player. Why shouldn't players carry their own bags, then? Or rake their own bunkers? Make their own yardage books or walk off their own yardages? I don't know how you decide that these things are okay for a player to have someone do for them, but not others. I have to make the shot or putt. Doesn't matter if someone points me in the right direction, I still have to make that shot. Isn't that the point of golf?
Of course it matters, because it's using their skill and not yours. They still have to hit the shot, of course that's true, but if you pick the wrong line or club then it doesn't make a difference how pure you strike it. Look,Tour golf isn't a team game, its as simple as that really.
