It’s essentially now or never for the New Orleans Saints. After a season in which some thought they would make a deep postseason run, the Saints need a victory to keep their slim playoff hopes alive in the NFC.

Tonight the holy men are in Chicago to do battle with a Bears team that is in desperate need of a win themselves. The Bears remain one game behind the Minnesota Vikings in the NFC North and considering the Vikes are likely to start backup Tarvaris Jackson at quarterback on Sunday against Arizona, a win over New Orleans could leave Chicago tied for first in the division by Sunday evening.

But nobody outside of Chicago expected too much from the Bears this year. The same cannot be said for the Saints.

In the offseason, New Orleans made a great effort to rebuild their beleaguered defense by adding LB Jonathan Vilma (trade/Jets), DT Sedrick Ellis (draft/first round) and CB Randall Gay (free agent/Patriots). The moves were supposed to be enough to keep opponents in check while the explosive Saints’ offense put up 30 points a game. But while the offense has done its part (No. 1 in the NFL in total yards), the defense has yielded just over 25 points a game and ranks in the bottom half of the league in stopping the run (20th) and pass (26th).

Part of the issue this year has been injuries as both Mike McKenzie and Charles Grant, two starters, have missed more than half the season. But the main issue for the Saints has been a lack of consistency – on both sides of the ball. The defense has done a decent job of loading the box and taking away the run at times, but then leaves itself vulnerable to opponents’ passing attacks. And up until last week when they beat the Falcons, head coach Sean Payton has been publicly criticized for abandoning the run and not having enough offensive balance.

A win tonight in Chicago would go a long way in saving the Saints’ season. It won’t be easy – Solider Field is a tough environment to play in December – but the Bears have only beaten one quality opponent in their last seven games (Week 7 vs. the Vikings) and have struggled mightily with consistency themselves. The key will be weather or not Payton will show the patience to stick with the run against a Bears’ defense that has been solid in taking away opponents’ rushing games. If they can, Chicago has proven that its not afraid to give up the sideline route and has had issues all season putting opponents away when they have a lead. And can the New Orleans defense force Kyle Orton to make mistakes? If they load up to stop Mike Forte, they better get pressure on Orton because he’s had success throwing vertically this season.

Should be a good one.
