FOCUS ON FIVE STORY LINES

1 Second-half horror stories Philadelphia at San Francisco

The 49ers pass defense has struggled mightily this season, and that leaves an opening for Eagles quarterback Nick Foles. San Francisco has been outscored 52-3 in the second half of games.

2 Can the Packers pass again? Green Bay at Chicago

Both teams had trouble stopping opponents' run games, so this could end up being a high-scoring tilt. The Packers' usually potent passing attack ranks 21st in the NFL. It's the 189th meeting in the league's oldest rivalry.

3 Strange uniform for Smith Ø Carolina at Baltimore

Former Panthers star receiver Steve Smith is now with the Ravens. Carolina dumped Smith after 13 seasons, and he said, "My wife cried, my kids cried. They didn't see me; I shed a few tears."

4 Brady's short game fine, but … New England at Kansas City

Tom Brady's long passing game — he's only 1-for-17 on passes longer than 20 yards — appears to be missing. The Chiefs, who have lost four home games in a row, have a chance to get back on track in this Monday night battle.

5 The scoreboard will be used New Orleans at Dallas

Everyone is expecting a high-scoring game … when the teams met last year, the Saints set an NFL record with 40 first downs.
