Heading into Week 4 of the 2015 NFL season, there were four teams without a win. Now, the Detroit Lions are the league's only winless team.

The Baltimore Ravens were the first winless team to record a tally in the win column in Week 4, as they took down the Pittsburgh Steelers in overtime on Thursday night. The Chicago Bears picked up a win against the Oakland Raiders on Sunday afternoon, and the New Orleans Saints got on the board with an overtime win against the Dallas Cowboys on Sunday night.

The 0-3 Lions take on the 1-2 Seattle Seahawks on Monday night. The Seahawks won't be an easy opponent, but this is a must-win game. If the Lions lose, they'll be the only team in the NFL to start the season with an 0-4 record.
