DT -- Bryan Robinson was supposed to be more at home inside after he moved from DE, but he hasn't made much of an impact, doesn't provide much pass rush and is not a stout run stuffer. Alfonso Boone can stuff the run, but he may not have the quickness or athleticism to thrive in Ron Rivera's defense. As rookies last season, Tron LaFavor and Ian Scott didn't look to be much more than backups.
DE -- Eighteen team sacks last season placed the Bears dead last in the NFL. Alex Brown was a dangerous pass rusher in college, and he had a team-best 5 1/2 last season. The Bears need more from DRE, and Brown might be able to provide that if he continues to improve and shows more quickness after losing 10-12 pounds. DLE Michael Haynes was a pass-rushing terror at Penn State but had just 2 sacks last season. Getting smaller this season should help him, too.
WR -- David Terrell, the 2001 first-round draft choice, has only on rare occasions shown he deserved to be taken eighth overall. Rookies Justin Gage and Bobby Wade showed promise last season, especially considering they were fifth-round picks. But the Bears would love a wideout with home-run potential to complement Marty Booker, who excels at working the middle of the field and underneath the coverage.
OLT -- The Bears spent $33 million this year for right tackle John Tait and $26 million a year earlier to keep center Olin Kreutz from leaving in free agency. But they still haven't solved the problem at left tackle, where they've been taking on water for several years. Qasim Mitchell has potential, but that's not enough to protect Rex Grossman's blind side. Mike Gandy is better suited to play inside, although he filled in at OLT last year and most of 2002.
LB -- They've lost talented players Rosey Colvin and Warrick Holdman in each of the past two seasons, leaving a gap in the unit that has Brian Urlacher in the middle and Lance Briggs at one outside spot.
