It's an inidication of a critical weakness... they have been HORRENDOUS at getting schemed pressure, where the team last year was good at it. Having to blitz a guy you know kills blitz because you are unable to scheme pressure any other way is a failing.
This statement is contradictory/wrong in a few places.
First, blitzing
is a way to scheme pressure. It's probably the primary way teams scheme to get pressure. What other schemes are you thinking the Patriots should have implemented? I suppose they could have had linemen stunt or dive specific gaps (and maybe they did), but considering they were getting destroyed in the running game and stunting/diving gaps can turn a bad run defense into a putrid one, I can understand why they didn't want to do this (or pivoted away from it in the first half). Maybe they could have disguised their coverage more, rotated coverages more frequently, etc, but...I mean, I have no idea how often they were doing those things during the game. Do you have that insight?
The other issue with your statement is that you're connecting their success last year to essentially, "better schemed pressures, less blitzing" (paraphrasing/summarizing). The defensive play calling is definitely not maximizing the talent on the team, but the biggest issue is that the front 7 suck at getting pressure. They ranked 28th in sacks last year, 31st in QB knockdowns. Counter to your statement, they did that while blitzing the fourth
most - 35.2% - in the NFL. Last years blitz heavy strategy lead to a high hurry rate (4th highest) as QB's rushed to beat the blitz pressure, as well as shorter yards per attempt (7th), low Air yards (9th), and great YAC (4th) as WR's don't get to develop their angles/routes. Last year, the coaches knew they were going to struggle getting pressure without the blitz, so they opted to go blitz heavy and force QBs to make short/easy passes - if they could make the read in time. Essentially, a typical BB defense - make the other team execute consistently for the length of the field.
This season, they're blitzing significantly less - 22.5% - and I attribute that as the primary factor in the slip on defense. While their overall sack/pressure numbers remain similar to last year, their hurries have now dropped as well. What does that mean? Duh. The extra time given is allowing deeper routes to develop and for teams to take bigger chunk plays out of the defense. They've gone from 9th best in air yards to 6th worst. 7th best in yards/completion and yards/attempt to 9th/10th worst respectively.
The players are largely the same, the DC (Covington) and HC were with the Patriots last year, as were both secondary coaches and Hightower (ILB). Theres continuity across the board, so I don't think theres been some seismic shift or drastic change to the defense that would imply this drop-off. I'm of the opinion the team should blitz more consistently, but with less sellout blitzes like we saw yesterday.
Other than that? The game yesterday didn't really tell me much about the defense that we didn't already know. They lack talent, and if the coaches aren't going to be skilled enough to maximize the talent they do have, then they better find some fucking talent ASAP.
