Hint: the list is short. When teams start 0-4, it is historically extremely difficult to recover and make the playoffs.

Those teams that opened 0-2 have a slightly better chance to make the postseason than those starting 0-3. Since 1990, 279 teams have started 0-2. Of those, only 32 have made the postseason. That's 11.5%. Of those teams, only 17 won their division (6.1%) and three won Super Bowls (1.1%).

Through two weeks in the NFL season it's difficult to separate the contenders from the pretenders. ESPN's FPI calculates each team's current playoff odds -- it hasn't updated the New England Patriots and New York Jets odds after Thursday night's game -- and right now 15 teams have higher than 50% chance to reach the postseason.

Another NFL Sunday is here, this time in Week 4, with a full slate of games to watch and enjoy. That’s right, it’s time for some football! And if you’re here, you may be wondering who is calling the game you’re watching.

The Week 4 of the NFL will conclude with some exciting match-ups on Sunday, September 29. Despite four teams boasting 3-0 records, none — not even the reigning Super Bowl champions, the Kansas City Chiefs — have looked invincible.
