Adam Schein, a so-called expert, has published his predictions for the 2006 NFL season. No one expects people to be dead-on with predictions like this, but the problem is that Adam's predictions are literally impossible.
There are 32 teams in the NFL that each play 16 games - for a total of 256 games. Each game has a winner and a loser, so the overall league must have 256 winners and 256 losers.
Adam's predictions, however, work out to an overall league record of 254-258. Oops.
