* PRO: Confident, determined. Won't hesitate to go across the middle to make a tough catch.
* CON: Has never lived up to No. 1 pick status. Immature and lacks the leadership skills the team must now have with Marty Booker gone.
* BACKUP: Justin Gage.
* PRO: Great size at 6-foot-6, 355 pounds. Promising prospect showed signs of potential by finishing 2003 as starter on left side.
* CON: Inexperience. Mitchell is a former undrafted free agent who is being asked to protect the QB's blind side.
* BACKUP: John Tait.
* PRO: Experience. The eight-time Pro Bowler established himself as one of the best while playing in Buffalo. * CON: Lazy. Brown was a backup through training camp until Terrence Metcalf went down. Needs to play hard all the time.
* BACKUP: Terrence Metcalf.
* PRO: Still known around the league as one of the best and most durable centers. Great leadership skills.
* CON: Undersized. Kreutz has trouble with oversized D-linemen and sometimes has to rely on double-team help.
* BACKUP: Terrence Metcalf.
* PRO: Versatile. The Notre Dame product is sharp and durable enough to play guard or tackle.
* CON: Consistency. Gandy has been moved around so much he's yet to establish himself at one position on the line.
* BACKUP: Ruben Brown.
* PRO: Experience. The veteran started 33 consecutive games with K.C. the last two seasons.
* CON: Tait battled a groin injury all of training camp. He's also got to live up to a six-year, $33 million contract he got this off-season.
* BACKUP: Aaron Gibson.
* PRO: Soft hands, decent size and good speed to catch short passes and turn them into big plays.
* CON: Injuries. Clark has yet to stay on the field. He's been slowed of late with a hamstring strain.
* BACKUP: Dustin Lyman.
* PRO: Clutch play. Half of Wade's receptions last season came on third down and resulted in first downs.
* CON: Inexperience. The second-year pro is taking over for Marty Booker and he's never started an NFL game.
* BACKUP: Bernard Berrian.
* PRO: Quick release, strong arm, and great leadership skills.
* CON: New offense, new coaches, fairly new quarterback. This is Grossman's team to lead, but he still hasn't proven anything.
* BACKUP: Jonathan Quinn.
* PRO: Strong, quick runner who has shown he's perfect for the new offense when it comes to running and catching the ball.
* CON: Much like Terrell, has never lived up to first-round potential. Jones needs to get it right with his third NFL team.
* BACKUP: Anthony Thomas.
* PRO: Great blocker who has shown he can catch the ball and star on special teams.
* CON: Still young and inexperienced. The former undrafted free agent played linebacker in college and is still growing at fullback.
* BACKUP: Jason McKie.
* PRO: Most accurate kicker in Bears history (77.9 percent). Has converted an NFL-high 46 FGs over 40 yards the last four years.
* CON: Edinger can't get kickoffs into the end zone and usually gives opponents great starting field position.
* BACKUP: Brad Maynard.
BEARS ON DEFENSE
* PRO: Led the AFC with 15 sacks last season and is very good against the run. Should help a team that had only 18 total sacks in '03.
* CON: Ogunleye held out all of training camp in Miami. Some think he also benefited from having Jason Taylor on the same line.
* BACKUP: Michael Haynes.
* PRO: Great first step, fast motor. Harris has all the tools to eventually be an All-Pro.
* CON: Rookie. Harris is a first-round pick, but will need some time to learn the position.
* BACKUP: Terry Johnson.
* PRO: Is an effective run defender. Has lost weight, which could improve his speed.
* CON: Pass Rush. Is not the typical defensive tackle in Smith's scheme. He isn't known for getting to the quarterback and will not play in the nickel defense.
* BACKUP: Terry Johnson
* PRO: Led the team in sacks with 5 1/2 in '03. Plays hard on every down and is more than adequate against the run.
* CON: Brown has been out with a calf injury most of training camp and is being pushed for his position.
* BACKUP: Michael Haynes.
* PRO: Great special teams player and a guy who has a knack for always being around the football.
* CON: The Purdue product had a groin injury that spoiled his rookie season. Needs to stay healthy to win over coaches.
* BACKUP: Marcus Reese.
* PRO: The name speaks for itself around the league.
* CON: Hamstring injury on the first day of training camp has set him back. Has been challenged to make the big plays.
* BACKUP: Hunter Hillenmeyer.
* PRO: Showed what a talent he is by taking over the job in his rookie campaign last year, starting 13 of 16 games.
* CON: Still young, Briggs hasn't come close to reaching his potential and needs to show last year wasn't a fluke.
* BACKUP: Leon Joe.
* PRO: As a rookie last season, Tillman turned into the team's best cover man. Great one-on-one skills and ball awareness.
* CON: Tillman still doesn't know all the ins and outs of playing corner. Needs to keep working at his craft and prove he's legit.
* BACKUP: Todd McMillon.
* PRO: Veteran corner with great speed and instincts. He's also the team's best punt returner.
* CON: Forced to step in for the injured Jerry Azumah, McQuarters is not a premier cover man and will be picked on by teams.
* BACKUP: Nathan Vasher.
* PRO: Physical player who is solid against the run, adequate against the pass and is always one of the team leaders in tackles.
* CON: Staying healthy. Neck injury cost Green six games last season and Bobby Gray has pushed him for the job.
* BACKUP: Bobby Gray.
* PRO: Big hitter and team's vocal leader on defense. Brown has started 63 of 64 games with the Bears.
* CON: With only two interceptions last season, some wonder if Brown has lost his touch as a playmaker.
* BACKUP: Todd Johnson.
* PRO: Great accuracy on punts and ability to pin opponents inside their 20-yard line.
* CON: Weak leg. He's got the touch, but not the distance when team's in a pinch.
* BACKUP: Paul Edinger.
