QUARTERBACK: F Jason Campbell didn’t get any help, but for $3.5 million, he has to be better than that. Campbell was totally outplayed by Colin Kaepernick — finishing 14-for-22 for 107 yards, 1 TD and 2 INTs for a 52.7 rating.

RUNNING BACKS: F Matt Forte got off to a great start — 8 yards on his first 2 carries — but was obliterated by the offensive meltdown after that and finished with 63 yards on 21 carries. Michael Bush (5-9) had an 18-yard gain on a screen pass.

RECEIVERS: F Whose fault is it that Bears receivers can’t get open while 49ers receivers get all sorts of separation. Brandon Marshall’s numbers (2-21) were eerily similar to the Packers game (2-24).

OFFENSIVE LINE: F Is there anything lower than an F? The offensive line was a disaster from the first time Campbell tried to drop back. The line looked totally unprepared. The worst sign for the Bears is that at this time last year, the line was getting

DEFENSIVE LINE: F The effort was there, but results were virtually nonexistent. Yet another part of the team that looked like it was totally outfoxed. By the time Corey Wootton and Israel Idonije shared a sack, it was too late.

LINEBACKERS: F Brian Urlacher made a couple of plays, but it seemed more out of frustration than game-planning. Urlacher was among many who missed tackles on a dreadful night.

DEFENSIVE BACKS: F It was only one game, but a lot of people probably want their Pro Bowl votes back after this debacle. Major Wright took a big step backward. Kelvin Hayden was burned for a 57-yard pass that helped set the tone.

SPECIAL TEAMS: F Decent coverage isn’t enough to bail out special teams. Devin Hester’s nine-yard loss on a punt return that looked like 15 or 16 yards told the story of the game.

COACHING: F With the Campbell-Kaepernick disaster leading the way, the Bears were outcoached on several levels. Jim Harbaugh makes it look so easy — the 49ers block, tackle and get open. Is it that difficult?
