Shivas, if you played golf with the guys you grew up with and none of you left the area even on vacation, no golfers from elsewhere visited and there was no TV, you might think you are hot shit to shoot 2 over par on a good day, and everyone else would agree. Then one day Tiger Woods comes to town and shoots a 63 and you find out you ain't all that after all. Were you skilled before Tiger came to town? Are you still skilled after you've seen that it is possible to play far better than you ever believed anyone could? It all has to do with who you compare yourself to.
I think skill relative to others and skill relative to your own limitations are two different things. I used to be unbeatable at quarters in college, I've made over a hundred in a row into a standard shot glass on more than one occasion. I felt like I was pretty skilled at it, but I never had the Tiger Woods of quarters come to town and show me what was possible.
Given that the free throw record is like 3000 in a row or something insane like that, and free throws are harder than quarters, I'm sure there's some guy (probably last name of Blutarsky) who could keep going for a whole weekend without missing once. If we redefine skill in quarters to encompass more than just into a shot glass, and talk about a "course" with a mixture of shot glasses, drink glasses, pints, pitchers, double bounce shot glasses, bank shots off purses, etc. then maybe Blutarsky isn't the best in the world anymore and someone else becomes most skilled.
