We simply need to get better on pass Defense. LB's, Corners, and Safeties need to stop giving everyone 5 yards of cushion. I have no faith in Tucker to hide our weaknesses with good scheme.
My only hope is that the DL does get pressure on every play, because if there's no pressure we can't cover anyone for more than 2 seconds.
No QB pressure and no turnovers = bad time
I hope so too, but I hope even more that the defensive line can actually get to the QB a little more often. The Bear got pressure last season, especially from the DE's but they couldn't get to the QB. I would debate that most of that can be attributed to having names like Landen Cohen at DT. I'll take pressure if nothing else, but after a while a defense earns a rep. Teams either see them as a defense that can make an offense pay, or just be the occasional distraction of the edges that the Bears were last season.
I don't expect a ton of sacks, but if the D-Line is only going to get pressure than it MUST come from the interior. There's pressure off from the edges, & then there's pressure from the interior that QB's go bat shit crazy over. When a DE pressure the QB, the QB can often still keep an eye on his reads, step up & make his completion. However if your DT's are effective & gets that pressure right in the face of the QB, & cuts off the pocket, the QB has no choice but to take his eyes off from his reads, scramble, get himself set & go through his reads all over again. I like the idea of pressure, but the defense to get it from the interior which it didn't do last year. Our DT's couldn't maintain control over the A & B Gaps, & I do think as a result it effected the play of the DE's..
I don't want to sound like pressure doesn't help, it looks good on spread sheets, & it is a must. But we have to hit the QB more often so he doesn't get comfortable. Look at Clinton McDonald DT formerly of the Seahawks. Last season he was one of the best 3-Techs in the game & he along with Mebane made one of if not the best DT/NT tandems in the league, & by no means did McDonald dominate with sack totals having 6 sacks. He applied constant pressure also in the face of opposing QB's, held his gap & played excellent against the run. This allowed Irving & Bennett to make life miserable for opposing QB's off the edges.
Getting nothing from our DT's & pressure off from the edges isn't going to get the defense anywhere. They need to get pressure from the interior, & sacks/hits/hurries from the DE's as a result of that interior pressure. Unfortunately, going back to the OP's diagram spreading out the front 4 in a wide 9 isn't going to help the ability of the defense to do this, at least with the smaller personnel.
Unless you have a monster shade like Dareus, Ngata or Wilfork in his prime at the shade I wouldn't want any part of kicking a 30 something DE out to the 9. Get in a tighter 4-3 under & bring that DE in a bit as a 7 Tech & trust LB to his job at the second level. With this personnel I would prefer the Under base with 5-1-3-7 gap techniques. If the One/Shade does what he's supposed to & draws the double from the C & RG, this helps the chances of freeing up the one on one for 3-Tech vs the LG off the A gap, & also one on one for 7 Tech RDE to attack the inside B gap or the open/closed C, which then allows the WILL playing to the 3-Tech to assume & maintain responsibility for whichever Gap the RDE doesn't attack whether it's the interior B or open/closed C (Whatever the play calls for).
Now to the strong side of the Shade, again if the Shade is able to do what's asked & draw that double from the C & RG, the 5 Tech will have to bend the edge so that the SAM can jam the flat cleanly. The 5 Tech must stay patient & must keep contain, & not release to go for the QB unless it's a stunt. Otherwise the lineman will attack the Sam at the second level & the QB or HB is probably going to run for a fat gain if the 5 fails to get to the QB. IZZY did this in the 2012 Seattle game & they made the Bears pay hard for it.
The Wide 9 without a potent shade is crazy & with the wrong personnel is basically an open invitation for interior linemen to go to the second level. If you can't draw that double the 9 is spread too way to far & the LB is going to get destroyed on the counter by the Guard at the second level. I think the Bears personnel up front best fits the 4-3 under & that is what they should base their defensive system around, & with some new wrinkles in the 2 gap sub that they have been tinkering around with.
