The Oakland Raiders’ playoff chances are hanging by a thread. The team enters Week 17 of the 2019 NFL season still alive in contention for the AFC’s No.6 seed, but they need a ton of help in order to reach the postseason.

Oakland can make the playoffs by beating the Denver Broncos, in addition to getting losses from the Tennessee Titans, Pittsburgh Steelers and Jacksonville Jaguars. The Indianapolis Colts are favored to beat Jacksonville. It’s not nearly as likely that the Houston Texans will beat Tennessee or that the Baltimore Ravens will top Pittsburgh.

Houston has already won the AFC South title with no chance of a first-round bye, though Texans’ head coach Bill O’Brien has indicated that his starters will still play. Baltimore has made it known that starters like Lamar Jackson, Mark Ingram, Marshal Yanda and Earl Thomas will rest. The Ravens are the AFC’s No.1 seed no matter what happens Sunday.

It’s a long shot that the scenario Oakland needs will come to fruition. What are the exact odds?

The Raiders have +155 betting odds to win in Denver. The Texans’ moneyline is also +155. The Ravens are given +110 odds to beat the Steelers. The Colts’ moneyline against the Jaguars is -185.

If you put all four of those teams into a moneyline parlay, you get 20/1 odds.

For comparison, the Miami Dolphins are 15.5-point underdogs on the road against the New England Patriots Sunday afternoon. Miami has 8/1 odds to win straight up.

There is actually a scenario in which the Raiders, Texans, Ravens and Colts win and Oakland still doesn’t make the playoffs. But that almost certainly won’t happen, considering it’d take victories from the Dolphins, Minnesota Vikings, Kansas City Chiefs and Green Bay Packers.

The Raiders kept their slim playoff hopes alive in Week 16 by beating the Los Angeles Chargers on the road as both the Steelers and Titans lost. It snapped a four-game losing streak for Oakland.
