Knox is the perfect fit in Mike Martz's offense

Some Bears players may want to burn the videotape from their game against the Chargers. Others may want to incorporate it — or parts of it — into their portfolio should they be looking for work soon.

It is difficult to judge units in a game like Saturday's because of the number of players who played and the lack of flow. So instead we'll focus on how some notable individuals fared after a review of the tape.

Al Afalava: He came on last year about this time, so he can do it again. But he didn't do it Saturday. It's hard to figure what has happened to this guy.

Getting called for pass interference in the end zone was bad enough, but Brian Urlacher Afalava also failed to block Brandon Lang when he lined up as the personal protector on the punt team. Result: blocked punt, safety.

Afalava did have an interception, but there was nothing remarkable about it. Chargers quarterback Jonathan Crompton threw the ball right to him in the open field. Alfalava should have had a nice return, but he fell down.

Devin Aromashodu: Yes, he can sit at the adults' table. If Aromashodu keeps producing the way he did Saturday, it doesn't make sense to keep him out of the starting lineup.

Kahlil Bell: The third running back spot remains up for grabs, but Bell Matt Forte made the most of his limited opportunities. He made a nice catch of a pass that was thrown behind him and turned it into a 13-yard gain.

Garrett Wolfe, meanwhile, failed to block Claude Spillman in a blitz pickup and was responsible for a play that easily could have been a sack or interception.

Lance Briggs: I don't think there is anything to worry about with this guy, but he dropped a potential interception and missed a tackle at the line of scrimmage on an 18-yard run.

If there is one criticism of Briggs' game, it's that he misses too many tackles. Missed tackles should be expected early in the preseason because the Bears don't practice tackling. Saturday was the first time any Bears defender tried to bring down a ballcarrier.

But the tackling needs to be cleaned up in short order.

Caleb Hanie: It took him a while to find his groove, but once he did Hanie seemed to relax and execute. He didn't lock onto receivers. He escaped pressure, rolled out and continued to survey the field — it paid off on his 7-yard touchdown pass.

Put the blame on his interception on him, however. Hanie held the ball too long — 3.9 seconds — before making a desperation throw under pressure.

Johnny Knox: Suspicions are confirmed. Knox is the perfect fit in Mike Martz's offense. He easily was the best route runner on the field.

Dan LeFevour: Let's face it, LeFevour was awful. He almost got his receivers killed on several of his passes. He had some bad overthrows. He didn't respond well to blitzes.

But LeFevour should be blamed for none of it. What should we have expected given the fact that the rookie, who needs more practice reps than anyone, has been given hardly any reps going back to minicamp?

What's more, his receivers were dropping passes and his protection was shaky. And the Chargers were blitzing him as if it were the Super Bowl.

Pisa Tinoisamoa: The aggression and speed with which he plays stand out. Tinoisamoa belongs on the field.

Nick Roach, with whom Tinoisamoa is competing for the strong-side linebacker job, also did some nice things. But he also lost containment on a run and failed to make a tackle he could have made.

Major Wright: If injuries have not settled the competition for the starting safety positions, Wright might have. He hasn't played enough for any of his flaws to be exposed, but he has shown he has the instincts to find the football, he gets there in a hurry and he's a sound tackler.

The Bears haven't had a safety like this in a while.

A couple of unheralded players who are fighting for roster spots also did some nice things. Undrafted free agent defensive end Barry Turner had some effective rushes. And linebacker Kevin Malast was very active with a team-high-tying seven tackles and a pass defended.
