No. 25 -- Chicago Bears The Bears were one of the teams that had only a couple of guys play well, whilst the others struggled and left their offense dead in the water. The "couple of guys" in this case were center Olin Kreutz and right guard Roberto Garza, with the rest being various shades of poor. None was worse than Orlando Pace and it was a huge mistake believing he had much left in the tank (he didn't). By the time he was benched in Week 13, the Bears were already gasping for air. Amazingly, as poor as a right tackle as Chris Williams was, he may end up being a success story if he can keep up his late-season form. Through the first 10 weeks of the season he was dreadful, giving up five sacks, eight hits and 24 hurries and throwing his hat in the ring as one of the worst pass protectors in the league. However, he did well against the Eagles in Week 11, did a reasonable job the next game (in Minnesota, of all places) and was then moved to left tackle to replace Pace, where he performed very creditably indeed.
Other players who have to step up their game are Matt Forte, who stayed in to block a league-leading 152 times but was among the top five worst pass-protecting backs last year (two sacks, a hit and 15 pressures); and Greg Olsen, who may be a decent receiver but struggles with all aspects of blocking. That has to be a huge concern considering the offense Mike Martz is expected to implement.
