The team's problem has largely centered on the offense, though, not the defense. The quarterback changes and gripes about offensive complexity -- NFL Network Insider Ian Rapoport reported Elway is frustrated with the offensive playbook being unwieldy -- have done little to fix what has been a hamstrung unit from the first week of the season. That the defense is bearing the brunt of Elway's attention might be more of a plea for Denver's strength to lift it out of the doldrums than actual criticism.
