Is this the best Bengals defense ever?

I know its only 4 games in. This D looks lights out. Even with a terrible offense. we really only gave up 10 to the Ravens. 1 was a first and goal from the 3 from a offensive turnover. A FG was from a offensive turnover as well. 13 to the Texans. 20 to the packers we get credit for scoring 7. Browns got a garbage TD late. After leading 31 to nothing. The Texans and Packers both have done much more when they weren't playing us. We have had some good defenses before this year but they all had a weakness I dont see 1 with this unit.
