It's hard to stay fresh and current all the time. Maybe the packers have tried to become too "cute" on both sides of the ball in their quest to keep things fresh and new or stay ahead of other teams. Like Rocky chopping wood and chasing chickens, sometimes you just have to get back to basics. Block better than the other guys, run better routes, tackle better, etc. I do like the theme here they are more than hinting at for the entire team. Better football play, less complexity. Simple works when you do the basics well. I'm going a ways back, but we've been a wrestling school since the 60's. We were good, they're still good. Gramby rolls don't win state championships other than by chance, single legs and escapes do with regularity. the first moves we ever learned when we were 5 and drilled over and over and over and over and over and over, you may get the idea. Football is no different.
The defense needs to get back to defending the field, attack at points, defend at others and just beat your man. Offense, line up, take your yards, beat your man, then take your shots. block, run, catch. Don't make it too difficult
Yep, the bottom line is always execution.
