The New Orleans Saints are still in the hunt for the NFC South crown.

At 4-8 that may seem outlandish. But in a division whose leader sits at 5-6, the door to the Saints sneaking into the playoffs is still wide open. That's why Monday may be the biggest game of the year — New Orleans has an opportunity to knock off the division leader.

But to do so, New Orleans needs its absolute best from its 35-year-old quarterback, Andy Dalton.

As things stand, the Saints' passing offense ranks 21st in points per game, 11th in passing yards per game, ninth in touchdowns, 29th in interceptions, and 14th in third-down percentage.

Through Week 13, Dalton has completed 66.4 percent of his throws with 14 touchdowns and 7 interceptions while averaging 225 yards per game. He's been efficient for stretches, but he's also struggled to get rid of the ball when under pressure.

Aiding Dalton is Saints rookie Chris Olave, who has enjoyed one of the finest seasons from a Saints rookie to date.

Olave leads the Saints with 56 catches for 822 yards. He's been a terrific route runner with excellent hands and deep speed. Adding to the play of Olave is that he's played well despite no other options.

Tampa Bay's defense

The pass protection has been iffy at best. And if Dalton gets hit early, he often struggles to get comfortable in the pocket. That may be bad news. The Saints are playing a Tampa Bay defense that has faired well against the pass.

Currently, Tampa Bay's defense ranks sixth in passing yards per game and seventh in points per game. The defense also has 36 sacks and 72 quarterback hits.

Establishing the run first may divert Tampa Bay from its all-out pass rush. From there, the Saints should establish a short passing game that doesn't require Dalton to hold on to the ball for too long. If they do so, New Orleans may just win its biggest game of the year.
