On the other HoF thread, someone asked who will be the first DoG player enshrined. I said it was Mooney, if for no other reason than he's so much older than the rest of us.
But he will be one of the "inner-circle" members of the Hall. Bill James, the baseball stat guy/writer/Red Sox employee, has studied baseball's Hall of Fame a lot, and we've drawn from his insights in crafting ultimate's Hall (disclaimer: I'm currently on the HoF Committee). One of the ideas concerns "peak" and "career" value.
Sandy Koufax is the classic example of a "peak" HoFer, someone with a short career (just 12 years in the majors, only six of them as above-average) but at such a brilliant high that you can't ignore him. Eddie Murray is a good example of "career", as he almost never led the league in anything but was pretty damn good for a pretty damn long time.
Well, Mooney is one of the tops in ultimate for both peak and career. His career value easily outdistances the rest of the field, even Kenny Dobyns, the only other player in the discussion when you combine your "peak" and "career" top 10 lists into "best player ever." (I write this only because I know neither of them will ever read this.)
It will be interesting to see how DoG and NYNY populate the Hall over the years. It will be a few more years until most of the core of those teams become eligible. As a rough guess, each team will probably have about five HoFers and another five guys who belong in the Hall of Very Good, guys who were either one of the very best for a short time or guys who were consistently excellent but never one of the elite of the elite. But these numbers really depend on how the Hall plays out.
A maximum of 5 players and contributors can be elected per year. There is currently a backlog of Hall-worthy players, so you'd expect that there'd be five new inductees each year, but it's possible that qualified candidates will split the vote and thus only three or four will be inducted. (There is a multi-step process to make sure that this isn't too much of a problem.) I'll guess without calculating that it will take 10-15 years for the Hall to be really current, such that the leading candidates in any given year will be those who just hit the minimum age (48 for men/45 for women this year, moving down to 43/40 by 2010).
It's an unfortunate reality that some of the early greats will probably not make it because of the dense field.
