Don't confuse a really good D for an overaggressive one. Will Witherspoon and Dan Morgan are smart linebackers that are good in coverage. They are not overaggressive. And Julius Peppers and Mike Rucker are talented defensive ends that are also pretty smart.
Against the Broncos, yeah Al Wilson is smart but DJ Williams and Ian Gold are generally just overaggressive, not smart. And their Browncos DL, you know they are not up to the task of staying disciplined and snuffing trickery. Also have an inexperienced safety there too.
The one weakness for Carolina is that Chris Gamble might not play smart, but that will be easily covered up I think and he's got a lot of natural talent.
Every game is not a good game to break out some kind of chicanery trick play. This game would be one of the worst games to try that on, IMO.
