Poor coaching and poor decision making (adjustments and personnel) by the coaches imho. Taking too long about making changes.
Not sure if your statement includes it, but I would put a lot of blame on Gute. Thinking he would have a successful season with the receiving room that he had.
Watkins and Cobb are proving that they are prone to injuries. Even in the 4 games Watkins has played, he has only made 9 catches for 150 yds and no TD's.
Lazard is about the only consistent WR, when healthy. However, besides his blocking skills being above average, the rest of his game is average or below. Definitely not a guy I would call a top #2 WR in the NFL.
The rookies, are just that, rookies. Doubs is the best of the 3 right now, but even he has looked like a rookie on a number of plays.
The Tight end group is lead by a great veteran blocker with Lewis. Tonyan is just meh and Deguara is looking like another failed 3rd round pick.
Why Gute and the Packers didn't see this coming years ago, is beyond me. It has been a slow motion train wreck and once Davante left the station, the derailment and subsequent crash was complete.
