THREE UP
1. Chargers: Won two in a row since return of RB Ryan Mathews but have a tough one Sunday at Baltimore.
2. Ravens: Justin Forsett, who averaged 282 yards rushing in his first six years since he was a seventh-round draft pick in 2008, is third in the league with 903 yards.
3.Bengals: Defense was terrific in back-to-back road wins, allowing 10 points to Saints, 13 to Texans.
THREE DOWN
1. Saints: Lost three in a row, all at home, to maintain their NFC South lead. Have a chance to become first 6-10 playoff team in history.
2. Titans: Lost five in a row. Wesley Woodyard has two picks, 1½ sacks and 69 tackles but defense ranks 32nd against the run (145.2 yards per game).
3. Redskins: It’s worse than 3-8. It’s 3-8 and franchise QB Robert Griffin III, who cost Washington three first-round picks and a second-rounder, already is history.
