Carolina might be a tougher test than Cincy, and Denver barely beat Cincy if you take out that 105 yd kickoff return TD. CAR has played well against some strong teams, just couldn't hang on to a lead at the end (Atlanta and CHI, Seattle also).
They're middle of the pack defensively, lower tier offensively, but seems to me they've played better than their record. Just f'd up badly late in games with offensive turnovers and game winning drives defensively. Denver will have to play well, can't get sloppy, lose the turnover battle, can't count on a 105 yd kickoff return for a TD again on the road.
