"105 total correct = 50% - what does that tell you?"
Well, (1) there are n=18 players, a very small sample. (2) Most of our games are virtually 50-50 odds (I think the data says that if the point spread is 9 or less, it's virtually even). (3) The points force games to be 50-50 odds. I like this plan because having cupcake games doesn't differentiate between the players. If you accept the fact that our games are virtually 50-50, as n goes to infinity, we should get exactly 50% correct. That is, unless one allows his/her team loyalty to defy the odds.
