Poor tackling is a persistent issue. 3rd and long is a persistent issue. Our offence going flat for swathes of game is a persistent issue since the bye (we're not going to score from every drive, but play calling and execution has seen more low moments post bye then before it).
And these are things which have carried over week by week. 3rd and long has now become a running joke.
We've done well so far, and our record is one which all but the Eagles would happily have. Looking back the Dolphins game was one of the most enjoyable of the season. But seeing similar issues crop up again and again is concerning, perhaps not for the Bears and Patriots, but more so for our game against the Bengals and going into the post season. And if we had lost on Sunday (little things went our way, and about time to) the concerns would be being discussed more freely than they are at the moment.
