While it might seem high for the Bears, looking at the current roster, I am leaning towards playing the over. Yes, I might be a little buyest, but I would never bet money with my heart. I actually believe the bears will win over 7 games. Here are a few reasons:
Justin Fields will be a much better quarterback
It has been well-documented that the biggest change in a QB development is almost always between year 1 and year 2. In fact, if you ask scouts and coaches when the majority of players make the biggest jump as professionals, they will often point to the period between their first and second year in the league. When you pair that up with the fact that Fields will now play under a different coaching staff, you could see a huge leap. Let's be honest, pretty much any qualified coach not named Matt Nagy will be an improvement.
The Schedule is very easy
Of course, you have to be careful throwing the word easy in the NFL. There is no such thing as an easy game. However, the Bears' schedule is actually very friendly at times. Here is a list of very very winnable games where I expect the bears to be favored in pretty much all of them except maybe Miami.
-Lions-Lions-Dolphins-Texans-Commanders-Falcons-Giants-Jets
For those reasons, I do believe the Bears will ultimately end up winning more than 6 games this season.
