I like Ben Johnson a lot and would love to pair him with someone like Jesse Minter from Michigan or Nate Dreiling from Utah for DC. He's extremely well spoken and oozes confidence/intelligence, the more interviews I've watched of him the more I'd be thrilled with him being hired. Let him basically be the OC ala McVay/Shanahan and allow a young, aggressive defensive coach reshape the core scheme. Honestly watching Michigan they have similar structure to what Pete runs, albeit with some more pressure, but a lot of cover 3/single high looks and those guys are coached to TACKLE man. So the scheme being brought in wouldn't drastically change, it'll just be a new voice preaching it. Very similar to Baltimore with Mike MacDonald (who I agree would also love, though he doesn't 'ooze' confidence how Ben does).
I will say - listening to former players they unanimously want Dan Quinn. Across the board they think he's grown from what happened in ATL and deserves another chance. He carries the same mantra as Pete and they feel the culture that Pete built will continue on under DQ. We can argue about Pete's message not reaching this roster (which I think JS will be taking a blowtorch to) but the outpouring of love for him shows what he built and attempted to continue on got guys to buy in. My only concern with him is wondering is he just an excellent DC rather than HC. There's been plenty of amazing DC's who flame out as a HC because it is such a different skillset managing the whole operation. He's fiery, gets his guys to buy in, is an amazing DL coach and defensive coach in general, and from what I remember never lost the locker room in Atlanta, even after it was starting to fall apart. If DQ hits a homerun on his OC and DC, I'd be alright with it.
