The Chicago Bears were one of the most exciting teams in the league to watch for a sizable portion of last season, and the innovative offensive concepts of rookie head coach Matt Nagy was one the biggest reasons why. Employing an extremely versatile offensive attack that maximized the strengths and limited the weakness of their personnel, the Bears averaged 26.3 points per game in 2018, the ninth-highest mark in the league.

As anyone who follows the NFL closely knows well, though, it wasn't offense that was the driving force behind Chicago's success last season. The Bears, led by Defensive Player of the Year runner-up Khalil Mack, led the league in fewest points allowed – an impressive statistic fueled by their unparalleled ability to clamp down on opposing teams in the red zone.

According to Pro Football Focus, Chicago surrendered a league-low 20 touchdowns in the red zone last season.

Don't expect the Bears to be any less dominant on defense in 2019, either. They'll miss longtime defensive coordinator Vic Fangio, now the head coach of the Denver Broncos, but replaced him with Chuck Pagano, who was integral to the Baltimore Ravens' supremacy on that side of the ball at the top of the decade. Chicago didn't lose any indispensable contributors, either, and its biggest defection, rock solid safety Adrian Amos, is being replaced by Ha-Ha Clinton Dix, hoping to enjoy a bounce-back campaign in 2019.

If Mitchell Trubiski continues making strides at quarterback, the Bears should be right back in the hunt for an NFC title this season, with a chance to win every game due in large part to a defense that never lets down.
