The two have a brief history in Atlanta. Miller sat on the bench, while Chandler was starting for the Falcons. Both veterans have a propensity for injury, thus the question now becomes who is the team's third quarterback.
The answer is Henry Burris, who signed as a free agent during the off-season. Meaning two of the three quarterbacks on the Bears roster are new to offensive coordinator John Shoop's system.
Still, Miller should have plenty of help to make the Bears offense an improved unit from last season when the team averaged 21.1 points per game. The offensive line, which allowed a league low 17 sacks, returns four starters. Anthony Thomas, who didn't get the ball on a consistent basis until week five, will be the starter on opening day. Marcus Robinson will add a deep threat the Bears missed most of last year.
If the Bears can keep Miller and Chandler healthy there's no reason Chicago can't make another bid for the division title and eventually a deeper run in the postseason.
