OK I did a quick PFR check. Let's include playoff games plus also let's include the Kansas City game in 2008 where Brady got the injury. The last home loss was Sunday, November 12, 2006, against the New York Jets. Since then...
2006: 4 wins (3 regular season plus 1 post season)
2007: 10 wins (8 regular season plus 2 post season)
2008: 1 win
2009: 2 wins
So that brings us to a total of 17. You don't suppose Marino is including the preseason?
