First of all, how to evaluate it. My method was to sum the squares of the differences in the standings from what someone picked and what the actual standings were. If someone picked the Cubs to finish third, you would be three off, and that would be squared and you would be charged nine points. Low score wins.
The NL West had two sets of ties, both for first and for fourth. So what I did was give people credit for picking either team in first or second (Padres and Dodgers) or fourth or fifth (DBacks and Rockies). For misses in that division, I gave everyone the benefit of a lower score. I was going to subtract 10 points for people who correctly tabbed the wild card team, but nobody picked either one (Detroit and Los Angeles).
