The Chicago Bears enter training camp with as many questions as answers in 2013.
In 2012, they became just the fourth team since 1978 of the league to start the season 7-1 and not make the playoffs, as they finished 10-6. That led to the firing of head coach Lovie Smith and most of his staff.
Under Smith, the Bears always seemed to be struggling to score points. The team replaced him with offensive guru Marc Trestman, whose most recent stint was in Canada with the Montreal Alouettes.
Trestman figures to install a more quarterback-friendly West Coast offense with a lot of assistance from offensive coordinator/line coach Aaron Kromer. Kromer comes to the Bears after serving as the offensive line coach for the Saints.
Former Jacksonville Jaguars defensive coordinator Mel Tucker has taken over for Rod Marinelli, who declined an offer to return. Tucker has learned the Bears system, but will certainly put his stamp on the team as well.
Although they return much of their roster, the Bears aren't without questions there either. Many players—including starting quarterback Jay Cutler—are in the last year's of their contracts.
For the 2013 Bears, it's time to either produce or move on as they're at critical junctures in their careers.
