Raiders HC Jack Del Rio holds his former team's offense out of end zone in 2015

Sunday was Jack Del Rio's first trip back to Denver to face the team with whom he was defensive coordinator the previous three seasons. It completed the season series between these two division rivals. It also completed a season shut out of the end zone by the Raiders defense against the Broncos offense.

It's the first time in the series history the Raiders have done that.

In their first meeting, the Broncos won 16-10 thanks to an interception return for a touchdown by Chris Harris and three field goals. Sunday, the Broncos scored 12 points; all off of field goals. Several times, they got inside the Raiders 10-yard-line, but each time they were stopped short and settled for a field goal.

Add the field goal that was missed and you have the Broncos making five trips into scoring position and not coming away with a touchdown. The Raiders, on the other hand, were able to score two touchdowns in the game and came away with the 15-12 victory because of it.

A big reason for the success in the red zone was the Raiders run defense which held the Broncos to just 34 yards on the ground. In their first meeting, the Raiders held the Broncos to 42 yards rushing. That's the fewest rushing yards by the Broncos over their season series with the Raiders since 1972 (51 yards).

The Broncos may have the NFL's best defense this season under new defensive coordinator Wade Phillips, but it's their former defensive coordinator who has been getting the best of them.
