Defensive backs who drop interceptions they have in-hand.
Experienced defensive backs who cannot cover (Archuleta is but one example).
Pass-rushing the defensive linemen on short yardage running plays.
Defensive players who forget to tackle when trying to strip the ball, forget to strip the ball when trying to tackle, or both.
The Cover-2 defense cannot cover Any-1... dump the scheme... we do not have the personnel to make it work.
Receivers who drop passes they have in-hand... looking around to see who's going to hit them.
Trading away a running back who could block in the backfield for his quarterback on passing plays, who could catch a pass out of the backfield.
Starting a running back who almost always takes that maddening half-step hesitation before moving forward, so he repeatedly gets creamed for no-yardage or short-yardage.
Starting a running back who does not know how to pass block for his quarterback... who does not know how to catch a football out of the backfield.
Starting a running back who just goes down too easy... there is no fire, no spark, no fierce drive. Walter Payton would ashamed if he turned in such a day's work.
Terrible offensive play selection...
Throwing the ball to receivers ten yards short of the first down on 3rd-and-long.
Being behind by more than one score and NOT taking a shot at heaving the ball down field with less than ten seconds to go in a half. Why? What harm??
What I'd like to see:
Adrian Peterson as starting running back. He runs tougher than the other guy, and he blocks better. He can also catch a ball out of the backfield.
Kyle Orton getting starts at quarterback (not as the "Savior-apparent," but because Grossman will need to be traded for his own sanity's sake as well as the Bears' sanity; Griese is not the future and is best used as a back-up).
Admitting some of the wrong guys were kept, and some of the wrong guys were traded.
Admitting the offensive line has not aged well and is indeed too old... time to rebuild here... they have not been effective running the ball, and pass protection breaks down too frequently (see also poor blocking by the starting running back).
Conduct a serious assessment of who is performing (or even physically and mentally capable of performing), and start deciding who to trade or release... clear away the weeds and dead wood now, and begin developing the guys who still show promise.
If truly key players are too banged up (Harris, Urlacher, Vasher, etc.), get them healthy, if not for this year, then next year. Give the newer guys a chance to develop, give the Bears a chance to evaluate the newer guys in game situations.
The few and far between bright spots:
