Currently we have 2 more playoffs left at the end of the 2018 and 2019 seasons. There are 4 teams left alive to win the title.
1. Patriots - 2 wins (Seahawks, Falcons), 2 losses (Giants, Eagles)
Sitting pretty with 4 super bowl appearances and 2 wins. They are in the lead but have not won it YET.
2. Eagles - 1 win (Patriots)
If they win the next 2 super bowls, they are team of the decade outright. However, if they win just 1 of the next 2, they could tie the Patriots with 2 super bowl wins apiece, and the Eagles will have a head to head win over the Patriots, so you could argue they are the team of the decade. This would be strengthened if they make both of the last 2 super bowls.
3. Seahawks - 1 win (Broncos), 1 loss (Patriots)
They have a shot to win team of the decade but they need to win the next 2 super bowls. They DID make the playoffs so the dream is still alive. Russell Wilson is in his prime and they rebuilt their defense, so it is possible. They have a loss to the Patriots so winning just 1 more super bowl probably isn't enough to pass the Patriots.
4. Ravens - 1 win (49ers)
If the Ravens win the next 2 super bowls, they will stand as the only team with 3 wins and will win team of the decade.
All other teams are eliminated because they cannot reach 3 wins and even if they reach 2 wins, they probably wouldn't pass the Patriots who have 4 appearances. The Packers, Giants, and Broncos all just got eliminated because, while they all won 1 super bowl this decade, they can no longer win 3 because they missed the playoffs this year.
