After a pair of close games to start the season against the Atlanta Falcons and Tampa Bay Buccaneers, the Saints haven't had any trouble covering the spread, blowing out both the Arizona Cardinals and Miami Dolphins. The Bears will be a tougher challenge in Week 5 though, particularly in Chicago where the home team is 2-0 in 2013.
The Bears picked up their first loss of the year in Week 5 against the Detroit Lions, but didn't have much trouble scoring, racking up 32 points in defeat. Ranked in the top 10 in points scored and allowed, as well as yards gained and allowed, the Bears are a well-rounded group that will be tough for any team to beat.
With the line even, it's just a matter of selecting who will win the matchup, regardless of points. The over/under expects plenty of points from the pair of teams though, and is currently set at 48.
