Below lie my unofficial record of the performance of four prediction sites over the course of the 2012-13 NFL postseason, for both picks against the spread and over/under picks. Because picks were recorded mid-week and assessed with respect to the posted spread, they may not reflect the final decision made by each prediction site each week. That said, all had a fairly solid performance this postseason.
Accuscore: 14 wins, 6 losses
Football Outsiders: 7 wins, 4 losses (no picks made for Over/Under)
NumberFire: 12 wins, 10 losses
TeamRankings: 12 wins, 10 losses
For what its worth, there were 6 games in which all the sites agreed on a side or a total. Those best bets went a combined 4-2. The table with the picks (or a predicted total number of points) is shown below.
