If we stay healthy this defense is going to be night and day from last year.
I think for a most part people are really underestimating what Hardy is going to bring to the table. With development of Crawford (remember, he was coming back last year from an achilles tear, and playing in a new position), and Lawrence (he's looking pretty stout this year), and the addition of Gregory, I wouldn't be surprised if we ended up with 40+ sacks.
If Sean Lee is healthy, that's huge. I've said it before, he changes games. We were 2nd in the league in turnovers forced last year, he'll not only keep us up there but the guy is just a monster in pass defense. I don't know if I've seen a LB with more INT's/game.
Byron has some things to prove, obviously, but I think he'll be a significant upgrade over Moore in nickel, which we run the majority of the time. Wilcox was also much better last season, he's still developing and an improved pass rush will help his game as well.
Barring injury, our pass defense is going to be vastly improved. The pass rush alone will be fierce, a roaming game changing LB with a knack for INT's, and an upgrade at the third CB slot in our nickel package.
Some things to ponder:
We were #2 last year in TO's forced with a minimal pass rush, #6 or #7 in 2013 with that dumpster fire of a defense. Marinelli gets turnovers.
We were #28 in the league in sacks with 28. If our improved pass rush/defense is good for 1 additional sack a game over last season, that'd have put us solidly in the top 10 and probably top 5. With the complete lack of pass rush last season we all evidenced last season, I believe this is reasonable.
We averaged 4.2 yards per attempt on the ground, which was right in the middle of the pack. If we improved 0.2 yards per carry over last season, we'd be top 10. Detroit #1, Seattle #2 with 3.4 y/c, and NE was tied for #8 with 4.0 yards per carry.
QB's had an average passer rating of 88.5 against us (#15). QB's averaged 7.5 yards/attempt (tied for #20th with 6.9 y/a being top 10). For reference, Seattle had the #2 defense in yards/attempt, the Patriots were #15 with a 7.2 average.
Points Allowed is obviously the objective (as well as turnovers to give your team more opportunities for Points Scored) and both teams in the Super Bowl were top 10 in points allowed. (Seattle #1 with 15.9, New England #8 with 19.6). We gave up 22 points a game (#15), if we give up 1 point less per game an overage, we'd have a top 10 unit in Points Allowed.
If our can turnovers remain consistent, the additional pressure of the DL and overall improvement of the defense can result in 1 additional sack per game over last year, and the improved pass defense (from the numerous factors discussed in the beginning of my post) can result in a 0.5 yard/attempt improvement over last season it's reasonable to assume that our Points Allowed will be improved by 1 point a game. Additionally, an improvement of 0.2 yards in yards/carry with the previous improvement of 0.5 yards/attempt in the passing game, would improve our yards allowed by 30 points, making us just about top 5.
Make of that what you will. I just wanted to put the information out there for those that are interested. In my opinion, given the personnel additions this offseason as well as improvement in our own investments, these figures are not insurmountable. I'd actually reason that most are actually very realistic. We are not that far off, and some minor improvements over last season will take this defense from "average/poor" to "good/very good". With our offense, we don't need to be Seattle. A top 10 defense in most statistical categories as well as a continued Marinelli trait for turnovers and it looks like this could be the year for the next Lombardi.
