They certainly had pieces that the previous regime had difficulty maximizing value.
They also changed the design of the offense, hired a top drawer Oline coach, junked GR who Fisher would have kept (yes speculation on my part but the new regime didn't waste time), cut bozos like Kenny Britt and Brian Quick.
Brought in Kupp.
Brought in Whit to completely change the dynamic of the Oline. Kromer probably the guy that recommended they go after the Buffalo Center Groh? after that fails they get Sullivan to replace the gritty but overmatched Timmy Barnes.
Veteran studs on the oline give Goff time he didn't have and offensive design maximizes his strengths.
They junked hands of stone Kendricks and completely changed the mindset.
No more "middle school offense" quotes and scoring goes from historic low to 30 PPG.
The transformation was nothing short of remarkable. (In fact, my remarks prove that :-))
I think they believe they can do the same with the Defense.
Keep the core studs - AD, Brock, Joyner, John Johnson and build around to make it dominant.
I wouldn't bet against this crew.
