Actually it's only about 0.7 wins per year, see Advanced NFL Stats: Win Probability Forfeited 2012

In a 16 game season, .7 wins is a lot. But I think that's understating it, because it doesn't incorporate dynamic effects. On 3rd and 10, a team that knows it will go for it on 4th down might call a draw or screen to get it to 4th and 5. A team that knows it has 4 downs might be more likely to throw deep on first down. A team that strings together longer possessions will tire out opposing defenses.

The point is, sports teams leave wins on the table. IBBs is another good example
