who was at fault for the Eagles blown coverage on Jaden Reed's 70 yard touchdown well that depends let's look at the play call the Packer's motion into a 3x1 set with the tight end aligned in what's called a nasty split where he's very tight to the end man on the line of scrimmage the Eagles are running cover three buzz where the safety to the passing strength rotates down into the strong hook Zone while the safety on the weak side rotates to the middle post they're playing with spot drop principles as opposed to the standard matching principles we see from Vic fangio the strong rotation is also not typical in fangio's defense here is where the confusion comes in the Packers three receivers release vertical right away when the defense is in cover three and facing a trips formation typically the weak hook Defender will pick up the number three receiver running a vertical route back across the field in this scenario the weak hook Defender is linebacker noobe Dean this is a clear mismatch for the defense to have a linebacker carrying the number three receiver vertical and the most memorable example of this being exploited is from Devonte Smith beating an Ohio linebacker for a touchdown and the national championship this is exactly why fangio prefers to have his weak safety rotate this way he can have a safety play the vertical of number three instead of a linebacker the confusion is a result of the formation the Packers a line end with the tight end in a nasty split defenses playing cover three will often use a shove alert that is communicated pre- snap and then executed post Snap depending on the release from the tight end if the tight end releases vertical right away then the corner will gain depth with the tight end as he moves through his Zone and the weak hook Defender is responsible for number three as he releases vertically across the field but if the tight end doesn't release vertical like we see here then the corner will execute the shoveler and gain depth while looking for number three on the crossing route the safety can play shaded more heavily towards the trip side of the field and the weak hook player will match any shallow route coming back across while the weak flat Defender widens with any route to the flat but we don't see either technique here the shoveler either was made but not communicated and executed properly or the call was never made and the weak hook Defender just didn't carry number three vertical so to answer the question the only people who know who is at fault for the touchdown are in the Eagles building lone assignments littered the Eagles defensive film in week 1 but this is also a great example of why teams in week one aren't the same in week 18 look for the Eagles to correct these mental errors as they adjust to a new coordinator
