The team with a winning record that won't make it to the playoffs is the Chicago Bears.
The Bears are 4-3 and in 3rd place in their division. The Green Bay Packers are in the same division and they are undefeated. in addition, the Detroit Lions are 6-2 and ahead of the Bears in the standings.
There are 6 teams in the NFC who are all trying for a wild card spot. The Lions and the Falcons are the two teams that I think will make the wild card. I don't think the Bears will make it because they give up to many sacks and their defense is giving up a lot of passing yards. I do not think they will catch the Lions and the Packers. But maybe next year!
