The might have been down three of their core offensive weapons on Sunday: , and .However, it wasn't the story of the Lions' lo s to the . Instead, it was the struggles of defense, a common theme for most of this season.Seattle was averaging just 15.7 points per game prior to Sunday.Yet, Glenn's unit couldn't stop and the Seahawks' offense from the start.In fact, Smith & Co. opened up the contest with an 11-play, Gerrit Cole Jersey 75-yard scoring drive. It was capped off by a 17-yard touchdown pa s from Smith to tight end Will Di sly.And, it was just the beginning of defensive woes. team failed to get a single sack of Smith, and allowed him to escape the pocket way too easily all game long.The Seattle signal-caller ran for a season-high 49 yards and a score, and he was efficient through the air. He completed 23-of-30 pa ses for 320 yards and two touchdowns, en route to recording a 132.6 pa ser rating.He consistently was allotted an ample amount of time to pick apart defense.Additionally, on seven of those 23 completions from Smith, he connected with , the Seahawks' No. 1 wide receiver.Metcalf had a field day with Detroit's secondary, including third-year cornerback .It was worst game of the year in coverage, and he and his defensive back counterparts allowed Metcalf to record seven catches for 149 yards.That wasn't the worst of it for defense on this day, though.Instead, it came on a third-and-16 play, with 0:33 to play in the third quarter. had just scored to cut the Seahawks' lead to eight points, 31-23, on a 51-yard touchdown run from .So, momentum had begun to shift in favor of the , and they had forced Seattle into a third-and-long situation.Yet, on that play, drew up a blitz, and his defense proceeded to collapse like it had all game long.The were thrown off guard by the Seahawks' decision to call a run play, and as a result, no one was present on the third level of the defense to stop running back . Penny subsequently found the end zone from 36 yards out for the back-breaking score.Penny broke the hearts of fans gathered at Ford Field once again late in the fourth quarter.After the had cut the Seahawks' lead to three, 41-38, with a touchdown pa s from to , Penny and Seattle responded on the ensuing drive with a touchdown of their own. On a third-and-5 at 41-yard line, Penny gashed the Lions for a long TD run. finished the contest with 151 yards and two touchdowns (on 17 carries), and averaged 8.9 yards per carry.The defense was so porous Sunday that never had to punt, the first time in Seahawks franchise history that the team didn't have to punt in a game.It was a tragically poor showing from on the defensive side of the ball. And, with the performance, the have now allowed an average of 35 points a game, and have yet to play a solid four quarters of football defensively this season.In his postgame pre ser, expre sed his dismay regarding the lack of improvement from the defense.Listen, its frustrating. Its frustrating, and I have nobody to blame but myself," Campbell told reporters. "Its on me to handle it. Cant keep saying that, cant keep writing that. Were going to look at everything.It's hard for the offense to overcome such a subpar performance from the defense on a weekly basis, even with the playmakers that the team po se ses offensively (i.e. Swift and St. Brown).And, even with Swift and St. Brown mi sing in action Sunday, Goff and the offense Jeff Bagwell Jersey did more than enough to win, scoring a season-high 45 points in the contest. That should be a more-than-sufficient amount of points to win a game in the .Sure, you can bring up the fact that threw a pick-six, which obviously didn't help the case in their attempt to secure the Week 4 win. However, he also completed 26-of-39 pa ses for Alex Bregman Jersey 378 yards and four touchdowns, equating to a pa ser rating of 121.5.It's why you can't truly blame the veteran signal-caller for the lo s.Despite the disappointing nature of the defeat, vowed, after Sunday's game, to keep supporting his teammates on the defensive side of the ball."You keep supporting them, and it'll come around," Goff said. "We trust those guys, we trust those coaches, trust those players. And, I'll tell you one thing: I know what happens if you don't support them. It goes downhill real quickly. So, you know, if we want to stay in this fight and have any chance, let's stick together and remain a team."To me, if you're going to point the finger at anyone for Sunday's lo s, it has to be . He clearly didn't have his defense prepared for , who is nothing more than a competent backup quarterback at this point in his career.Yet, defense made him look like a high-end No. 1 QB. And, his unit also had no answer for and ground attack.So, it didn't matter what kind of output the got from their offense Sunday. They weren't going to stop Smith and the offense anyways.It's time to start criticizing for the ineffective play of the defense, which failed yet again in its Week 4 lo s to Seattle.Remember, Glenn interviewed for multiple NFL head coaching jobs over the offseason, and was thought to be carving a path to becoming a head man in the league one day.However, through the first quarter of the 2022 campaign, he has proven time and time again that he's far from head coach material.If landing a head coaching gig was even the slightest thought in his head, he needs to remove it immediately. The only thing he should be worried about right now is fixing the Lions' inept defense.
