What happened: Green Bay has opened the season at the bottom of the league in completion percentage and rushing yards per game. The last team to sit last in both categories through three weeks was the 1989 Dallas Cowboys.

Why it matters: An offense that cannot hit routine throws or generate steady ground production leaves itself little margin on early downs and third down. That kind of two-track inefficiency can turn a bad September into a longer climb before midseason.

What to watch: Week 4 will show whether Green Bay can climb out of the cellar in either category. Even a modest bump in one phase would break the historical comparison.
