NFL: Weekend preview

A lookahead to Week 15:

Dallas @ New Orleans: Can the Cowboys end the Saints' streak? Much will depend on the Dallas defense and how effectively they can limit Drew Brees and the balanced New Orleans offense. The Cowboys have lost two straight and now trail the Eagles in the NFC East, putting their playoff hopes in serious jeopardy. The Saints, already confirmed as division winners, have shown a few flaws in recent escapes against the Redskins and Falcons but home support should be enough to continue Dallas' December woes. Expect the streak to hit 14.

Miami @ Tennessee: Both teams remain in the playoff hunt, making this a critical clash. If the playoffs began today neither side would make the cut but the Titans are bringing a lot of momentum to the final weeks of the season. Meanwhile, the Dolphins bagged a big win over the Patriots and are within striking distance at 7-6. The running back battle could decide this one, though. Ricky Williams has shown he can still do a job for Miami at age 32 but Tennessee's Chris Johnson has rushed for over 100 yards in each of the last eight games and his explosive speed should give the Titans the edge.

Cincinnati @ San Diego: The Bengals have been rocked by the tragic death of receiver Chris Henry and could be forgiven for not being at their best in this one. The Chargers are rolling towards the playoffs with an eight-game winning run and Philip Rivers has been untouchable in recent weeks. It is hard to believe that San Diego were ever 2-3. Cincinnati have weapons of their own but are faltering at the worst possible time and the Chargers should be too strong, even if Chad Ochocinco has a big game.
