The wheels aren't falling off, but they sure are being held together by duct tape.

At 1-4, the Las Vegas Raiders have one of the worst records in the NFL. And to improve, Las Vegas needs to get back to what worked last season — converting in one-score games.

Last season, the Raiders went 7-2 in one-score games with a record four overtime wins and six walk-off victories.

Las Vegas thought it could build off last season's momentum by adding Davante Adams. But through five weeks, the inverse is true. In the last five weeks, the Raiders have lost four one-score football games.

That marks a franchise record.

In the season opener, the Raiders climbed out of a 14-point deficit but were unable to overcome Derek Carr's untimely turnovers in a 24-19 loss.

The following week, Las Vegas built a 20-point halftime lead. It didn't last. The offense stalled in the second half, the defense got tired and Kyler Murray and the Cardinals rallied to tie it on the final play of regulation.

In overtime, the defense got a stop but Carr missed an open Adams on a play that would have gotten Las Vegas into range for a game-winning field goal. And on the following play, Hunter Renfrow fumbled.

When facing Tennessee, poor red zone offense hampered Las Vegas, and a two-point conversion didn't go their way.

Then on Monday Night Football, Las Vegas blew a 17-point lead to the Chiefs, leaving a bad taste in everyone's mouth.

This season hasn't been one of dreams for Las Vegas. Last season, the Raiders found the magic. Now, it seems that the luck has run out.

If Las Vegas wants to turn the season around, it comes down to winning big in close games.
