We will just agree to disagree on this one. There are very few comparisons between this current defense and the 90s ones that were some of the best in football and sometimes referred to as one of the more underrated defenses in NFL history.
The fact there were misses by Johnson doesn't change the fact that the defenses in the 90s were built with upper echelon talent. The 90s defenses invested more into the defense than this current version.
Further, they didn't really need to "gel". They overhauled their defense in just two offseasons and did so with upper echelon talent. They added Castillas in 1991. Then in 1992, the year their defense was really good, they added two proven NFL studs in Everett and Haley (we acquired no players recently of their caliber) and then two #1 picks in Jones and Smith to the defense.
I hope you are right that this defense is really good, but there really is no comparison to the 90s defenses........... either in how they play or how they were built.
What seems to cloud the issue is the fact that they made the trade of the century and then another great trade of Steve Walsh, pretty much tripling their quantity of top picks for two to three years. This allowed them to accelerate the process but it was still the same process of drafting while trying to maintain value.
In any case, you win for now, which means that your opinion may be considered more relevant until we actually see some real games. In the end its the only way to find out.
But one more point before I go.
When all this was happening, when the JJ's were building that team one particular guy was paying attention. He had the best seat in the house while standing next to Jimmy holding a clipboard. He probably relies on that experience now and then.
