I’ve referenced it a bit here and there, but the nuts and bolts are this: In the years where the secondary was healthy, 2009, 2010, and 2012 they average 21 pts/g and 1.4 to 1.5 TO/g. I included 2009 and 2010 to show some years where the talent on defense was younger and probably more uniform throughout the unit. The point here is that IMO, this is the apex of what this coaching staff with talent can most likely achieve. So the question on the defensive staff as well as the Cover 2 scheme they run is if 21 pts/G and 1.5 TO/G are acceptable?
I think it depends on what kind of team you've built and what kind of offense and special teams accompany that defense. The Ravens just won the Super Bowl with comparable numbers. Here's what the past 5 Super Bowl winners have averaged on defense:
Baltimore: 21.5 pts/G; 25 turnovers (1.56 per game)
Giants: 25 pts/G; 31 turnovers (1.9 per game)
Packers: 15 pts/G; 32 turnovers (2 per game)
Saints: 21.3 pts/G; 39 turnovers (2.4 per game)
Steelers: 13.9 pts/G; 29 turnovers (1.8 per game)
I think having a high-powered offense can help increase the number of turnovers a defense is able to force. It doesn't always work out that way but a team with a terrific offense can often put opponents in "catch up" situations, making them one-dimensional, and that can lead to more turnovers.
A cover 2 scheme certainly doesn't prevent a team from forcing turnovers (just look at what some of Lovie Smith's Bears teams did in that area) and Frazier has coordinated a defense that had over 30 turnovers in a season so I think he's capable of fielding a defense that fits in the range of the Super Bowl teams above. I don't know if his approach could ever yield as little as 14-15 points per game or as many as 39 turnovers but personnel plays a role in that stuff too. It's a moot point in regard to Frazier because there's very little chance at this point that he and his staff will return next season.
Anyway, I think those numbers are acceptable but certainly not elite and the team should strive to become elite.
In doing the analysis I noticed that elite defenses tend to average 15-18 Pts/G and closer to 2 TO/G. So IMO, if we want to achieve elite status something needs to change.I’m not convinced that this coaching staff can do better than the above given what we’ve seen when “their” defense had a lot going for it (2009) as well as what we’ve seen when disaster hits (2011 & 2013.) Beyond this, I also think that the NFL is leaving zone defense behind. Basically the Cover 2 tries to force 3rd and long via a sack or stingy defense on 1st and 2nd down. As we’ve seen countless times, when you play a good to great QB, you get them 3rd and 17 and then our secondary gives up the long play in a soft spot of the zone and/or due to poor play by the secondary. Sacks are not reliable enough to get them off the field, unless they happen on 3rd down. (The best sack year was 2011, which averaged 4 a game, over the 5 years they average about 3.3 a game, which is very strong in the league.)
I'm not so sure the league is moving away from zone but I think it's getting away from the Tampa 2. Most teams still use a mix of man and zone coverages. If I'm not mistaken, Carolina's defense is predominantly a zone defense. I think Seattle runs quite a bit of it too and those are two of the better defensive teams in the league. Anyway, I think what needs to change, first and foremost, is the personnel, especially if you want the Vikes to move away from zone defense. Personally, I think a defense without quality personnel in the right places will get destroyed by a good offense, whether they're running a man-to-man scheme or zone. Some players play one scheme better than another but regardless of scheme, the skills it takes to excel on defense must be present and abundant or the defense won't be very good.
In short, they need to fix the coverage issues and do something to impact completion % as well as the take/give. To me that is the trend that NFL defenses are taking given the rules favoring passing offenses as well as the quality of the modern NFL QB. IMO this points to a need for a defensive philosophy/scheme change.
I firmly believe players trump schemes, which isn't to say scheme and coaching aren't important factors in defensive success but rather that the best way to force more turnovers and impact completion percentages is to find players who excel at forcing turnovers (like Tillman does for Chicago or like Ed Reed did in Baltimore), who excel in
coverage, who break down the line of scrimmage and play in the backfield, etc.. As I've been saying all season, it doesn't matter what scheme you ask players to run if they aren't good enough to make it work. Scheming and confusing offenses can certainly help lead to big plays but those plays and the takeaways we all covet are primarily the result of players winning matchups. An instinctive CB turns under-thrown passes into INTs. Chris Cook manages to fall in on his face and turn them into completions.

The best way to force mistakes from a QB is to pressure him inside, collapse the pocket and then force him out into what is hopefully an oncoming pass rusher.
What I care about is getting more big plays (Takeaways) and better overall coverage play. I’m not convinced this is going to happen under the current defensive mindset of this football team. In terms of Frasier can that change while he is at the helm? That I do not know, but if I’m Spielman/ The Wilfs that is the question that needs to be answered on Defense because IMO, the trend for this defense is going in the wrong direction, even when healthy.
They don't have the "horses". They really don't... I'm ready to see a scheme change but it's not going to make enough difference (if any) without better players. As I said above, I think Frazier's gone so to me the real question is whether the next coach up will have the players he needs to make his scheme succeed.
