Saints defensive film review vs. Bucs: Game makes you wonder ... how would Dennis Allen had done as defensive coordinator all season? _lowres

Advocate file photo by SCOTT THRELKELD -- Defensive coordinator Dennis Allen has overseen several improvements in the Saints defense since taking over in mid-November.

After reviewing Sunday’s win over the Tampa Bay Buccaneers, one has to wonder what Dennis Allen could have done if he started the season serving as the New Orleans Saints’ defensive coordinator.

Maybe it wouldn’t have been any different. Maybe the defense would have struggled all year and still crumbled under the weight of all the injuries in the secondary. But after seeing the game plan and how well he called the 24-17 victory, it’s interesting to wonder how different things might have been.

There’s little question this was the best called game of the season for New Orleans on defense. In his third game as defensive coordinator after taking over for Rob Ryan, Allen finally put his stamp on a game and there were a lot of differences in how the team operated from other games earlier in the season.

The biggest noticeable differences were in the coverages the team used. After operating primarily out of single-high safety looks with man coverage underneath, the Saints used a variety of different looks and did a good job of disguising them.

While the team still used several looks with a single-high safety, the Saints also mixed in several Cover 2, Tampa 2 and “inverted” Cover 2 looks. The defense also played more zone coverage than it typically does.

The mixing and matching of looks made it difficult for Bucs quarterback Jameis Winston to diagnose the defense, especially when New Orleans waited until right before the snap to show its coverage.

The end result was that the defense did not ever get beat on a deep pass. Winston only attempted two deep passes during the contest, neither of which were completed. The rest came on short passes and the Saints were often in position to quickly make a tackle.

It’s too soon to know if Allen will cure all that ails the Saints or if he can keep this up, but this game was a strong step in the right direction.

DEFENSIVE LINE: 2.5 out of 4

The Saints need to find Cam Jordan a running mate this offseason, whether it be at defensive tackle or coming off the other edge. He remains the only player who can generate consistent pass rush. He had a few pressures, a quarterback hit, a tipped pass, and a few good plays in the running game, including when he stuffed a run from the back side. … New Orleans remained aggressive in this game, blitzing on about 37.5 percent of Winston’s dropbacks, but the team struggled to get consistent pressure – especially when attacking with only four men. … Tavaris Barnes only played six snaps but managed to record a pressure and a quarterback hit. … Obum Gwacham owes linebacker Hau’oli Kikaha for creating his sack. The linebacker pushed him back into Gwacham. The bigger question on that play is what Winston was trying to do. It looked like he wanted to run but turned back after spotting Dannell Ellerbe waiting for him to take off. … Bobby Richardson flashed several times and was very good against the run. His best moment came on the second series when he shed an Austin Seferian-Jenkins block and stuffed Doug Martin. … Rookie Tyeler Davison showed a lot of promise last week against Carolina starting in place of John Jenkins. This performance was more mixed. He was cleared out a couple times on big runs.

LINEBACKERS: 2.5 out of 4

This wasn’t the best game that Ellerbe has played this season. He’s been better, but there’s something about his presence that makes the defense be more successful. In his first game back from sports hernia surgery, Ellerbe was pretty solid against the run. He fits his gaps better than his replacements and is quick to the ball. His performance in coverage was just OK. … Despite not having many “flash plays,” Stephone Anthony was very solid in coverage and his ability to drop back in zone was one of the keys to the defense being able to constrain Tampa’s passing attack. For example, in Tampa 2, Anthony is required to drop back and cover a deep third of the field. He also had a lot of responsibility in other coverages, both man and zone. While those things do not show up in the stats, they were huge for the defense.

DEFENSIVE BACKS: 3 out of 4

Delvin Breaux has really bounced back after a shaky performance against the New York Giants. In the five games since, he’s better targeted 16 times for five receptions and 33 yards. He was not thrown at against the Bucs until there was 4:41 remaining in the fourth quarter. The pass, intended for Mike Evans, fell incomplete. … Breaux was used in an interesting capacity in this game. New Orleans ran an “inverted” Cover 2 several times, with Breaux flowing up the field and serving like a safety and another player covering underneath. … Brandon Browner was left covering Evans several times and never gave up a reception. Overall, Browner surrendered two catches for 25 yards. … Evans finished with two receptions, one which came on Anthony (22 yards) and another on Damian Swann (17 yards). … Kenny Vaccaro had more deep responsibility in this game than what has become typical. It didn’t count as an official play since there was a penalty elsewhere, but he blitzed a put a nice hit on Winston on the first snap of the game. He was later flagged for roughing the passer. It looked like a bad call. Vaccaro was already in motion to tackle to Winston when the ball was released. … Kyle Wilson had a two penalties on the same drive. That can’t happen. … It was a good game for Jairus Byrd, who seemed to benefit from playing half the field at times. He broke up a pass intended for Cameron Brate that came out of a Cover 2 shell.
