You've been on this soap box for 3 years... and your argument makes sense to a point. GB doesn't have great talent in regards to depth. Let's just give you that point.
However the top 24/25 on the roster are comparable to any team in the league and 3 of those players could be considered elite. With that said both offensively and defensively we have to find an x factor.
Green bay defense was ranked 18th in total yards.... giving up 354.8 yards per game. Pass defense is ranked 27th per game and rushing 12th. Scoring defense was ranked 21st.
So no top 10 in the stats with an improvement against the run and a very poor pass defense.
Let's add in SNAFU after SNAFU on defense from not having the correct defense on the backside or just really poor calls vs teams that used man beaters or crossing routes to slice and dice his man over zones and combo covers.
While your "talent " argument has some validity this isn't college FB, everyone else is playing with that kind of talent pool. GB has allowed it's self to be lulled into the belief that having continuity in scheme or this years big revaluation to shorten and simplify the play calls will bring gold ?

Yes better talent helps but we have salary cap issues and other limiting factors. A very good DC knows how to scheme to his teams strength and make up for those limitations.
The Pitt 3/4 got us a SB ...great and dandy but at some point you have to move on schematically. That time is now.
