The Chicago Bears upgraded several key positions this offseason, but they still have holes and will need returning players to improve their play if they're going to take the next step and make the playoffs.
With the NFL draft and the bulk of free agency over with, the Bears basically know what their roster is going to look like. Some of the holes they had last season remain with returning starters expected to step up their play.
Although some of the newcomers will fill big roles and may be asked to play at higher levels than they did with their former teams, they're not included in this list.
Also not included is J'Marcus Webb. Webb has moved from left tackle to right tackle. Should he be able to play at the same level this year as he did last year, he'll be a huge upgrade on the right side.
This list is focused mostly on players who are returning to the same positions they played—and struggled at—last year.
While the Bears are looking to have different starters at four of the five spots on the offensive line, the one returning needs to be better. They also need more receiving options for quarterback Jay Cutler and a few defensive players need to be better than they were last year.
The Bears enter the 2013-14 season full of potential. On paper, they're as talented of a team as there is in the division. They need some of their returning players to be better than they were last year, and in most cases, there's evidence that they can be.
