I get that you believe traditionally the defense cannot risk attempting certain things. But just consider how our secondary has been constructed through acquisition and development. And when I say secondary, I'm focusing more on "cornerback" first, and then getting to your point about "safety".
Guys like Tramon Williams, Sam Shields, Davon House, and Ladarius Gunter would by most accounts be defined as true cornerbacks, regardless of their individual skill sets/playing traits. But think about some other guys in GB over the years that have filled the role of a "corner" in certain instances. Guys like Charles Woodson, Micah Hyde, and Damarious Randall. We all know C-Wood is the GOAT hybrid, Hyde was drafted as a hybrid, and Randall was essentially a safety that we made an outside corner when he came in as a rookie, even though ASU did somewhat of the opposite while he was in college. My point is, our defense has been designed (and coached/trained specifically to identify/accentuate specific players for probably a decade now or more) for certain guys to be able to act like safeties sometimes, while also at a flick of the wrist have the ability to act like a corner also.
With that being said, we look at positions like boundary/field corner and free safety as having primary assignments that require specific skills to be accomplished at a consistently competent level, besides blitzing. But I would venture to say that, when it comes to the positions of "strong safety/slot corner/nickelback/dimeback" the roles/responsibilities/objectives can be-at the minimum-binary based upon the formation of the offense and the defensive look/call. Therefore, certain multiple skill sets that can be added together within a single player (and sometimes even skill sets designed to compliment other players so they are working together as a unit/properly communicating with different positional groups within the defense as a whole) are required.
When you look at the four secondary positions I outlined, and then look at history and the players that have manned said positions, I think that the idea of a dime look for Green Bay with Dom Capers as DC and JW as a coach in the secondary having to have 4 Deion Sanders or Darrelle Revis or Richard Sherman or Davon House or Ladarius Gunter or Kevin King types on the field simoultaneously isn't necessarily what the staff/team wants. I would venture to say, though, that they wouldn't mind having 4 Charles Woodson types lined up together. Or 4 Micah Hyde types on their A-game with more athletic capabilities. Or 4 Damarious Randall/Quinten Rollins types when they looked great as rookies/Morgan Burnett on top of his craft with a little more speed + even better coverage skills, etc, etc...
Now, add in the reality that in our defensive scheme over recent years we have struggled at times with run defense up the middle, defending the deep ball, and communication lapses between the LBs and secondary that have led to big plays for the opposing offense, and you could see why having a Josh Jones (whom, by the way, was our second player drafted this year at pick #61-a high pick that means normally he's gonna play early and often/get every opportunity to by the team unless he can't) be a "super-hybrid" if you will-combining the skill sets of a Bucannon with AZ/Hyde with BUF now-may be part of what Ted/Mike/Dom/Joe have decided they need to attempt to embark on in order to improve. Which could possibly mean having a dime package that I previously described. The job of our coaches is to see what is going on in the league, along with what's going on with us, and provide solutions to give us the best chance to compete (especially on the defensive side of the ball, since we got AR as QB w/Mike running the O) for a chip. I can envision how having a dime look with Jones and Burnett inside could potentially not be good, or it could be exactly what we we need to do. I choose to think in terms of the latter, especially when you take into consideration Burnett looked great for the most part covering TEs man-2-man and in zone as a money backer last season/what Jones shows the potential of being coming from NC State.
