"Of all the valid reasons offered for why the Bears should avoid pursuing released quarterback Donovan McNabb, please resist any relating to McNabb's inability to function in Mike Martz's system.

Haven't we seen enough examples of that system systematically making it harder for the Bears to win games instead of easier?

Martz and his system just malfunctioned to create a six-point swing in a five-point loss. The system now has been reprogrammed soon after the start of each of Martz's two seasons so the Bears offense could function at a higher level. The system too often represents the root cause of the offense's most calamitous moments even if Martz prefers to blame his players for them — more on that later."
