In "Whatever Happened to the Hall of Fame" Bill James explained the "Keltner List," named after former Cleveland third baseman Ken Keltner: "I drew up a lits of questios that might be used to evaluate where a player stands as a potential Hall of Famer...but, because it involves a series of subjective questions, it doesn't necessarily work as a formal methodology."
There are 15 questions, and they require yes/no responses. I formalize the methodology for this project, by giving some of the questions greater weight, and some lesser weight. For instance "Do most players with comparable stats get elected" is given 1/2 the weight, because in my system Sim Scores get 1/2 the normal weight in the GPA. So a "yes" to that question earnst he player 0.5 points.
A question that gets 1.5 times the weight is "Was he arguably the best player in the league at his position?" because I think this is a very important part of evaluating Hall of Famers.
I then developed a scale that gives an A to anyone with 8 points or more, a B for 6-7 points, a C for 4-5 points and a D for 2-3 points.
It is subjective, but because it is arguably the real test of whether someone should be in the Hall, the Keltner Test gets the normal weight in the GPA.
