Divisional Showdowns: Arizona's probably a fraud, but the other six teams have a chance.

It's Divisional Playoff time in the NFL, the last weekend of four-game playoff weekends, and this one shouldn't be as close as last week's Wild Card Weekend.

In the AFC, it's all about defense, as the conference boasts the top three scoring defenses in the NFL (Pittsburgh, Tennessee and Baltimore) as well as the top scoring offense in the AFC (San Diego). In fact, when San Diego plays in Pittsburgh tomorrow it will be the first time since Denver (top offense) faced Baltimore (top defense) in the 2000 AFC Wild Card round that a conference’s top scoring offense will meet the top scoring defense.

Meanwhile, in the NFC, it's about two dominating 12-4 teams — Carolina and the defending Super Bowl champion New York Giants — going up against upstart teams that didn't win 10 games during the regular season (Arizona was 9-7 while Philadelphia was 9-6-1). 

So it's time to look closely at our four playoff games. Remember, all four NEVER come in the way the oddsmakers predict, so be prepared to consider an upset.

SATURDAY AFTERNOON

Baltimore Ravens (12-5) at Tennessee Titans (13-3)

Baltimore Ravens rookie head coach John Harbaugh and his rookie quarterback Joe Flacco can each reach milestones when they face the Titans this week. Flacco can become the first rookie quarterback to win his first two playoff games and Harbaugh can become only the fifth rookie head coach to reach that mark. This is our upset.

Take Baltimore

SATURDAY NIGHT

Arizona Cardinals (10-7) at Carolina Panthers (12-4) 

The Cards and Panthers boast 2008’s top two NFC receiving-yardage leaders in Arizona’s Larry Fitzgerald (1,431) and Carolina's Steve Smith (1,421). According to the NFL, Fitzgerald and teammate Anquan Boldin and Smith and teammate Muhsin Mohammad combined for 4,813 yards this sason, the fifth most in an NFL playoff matchup by the top two receivers of each team. I love Fitzgerald, but the question is: How good is Kurt Warner, really?

Take Carolina

SUNDAY AFTERNOON

Philadelphia Eagles (10-6-1) at New York Giants (12-4)

The Giants begin their postseason this week against their hated division-rival Philadelphia. Last year, the Giants won three playoff road games as the NFC’s fifth seed and, of course, they went all the way to a Super Bowl XLII triumph. This year, however, as the No. 1 seed, they have homefield advantage throughout the playoffs.  Of course, that's not likely to intimidate the Eagles. Philly beat the Giants 20-14 on Dec. 7 and have won five of its last eight at the Meadowlands.

Take NY Giants

San Diego Chargers (9-8) at Pittsburgh Steelers (12-4)

Pittsburgh has the No. 1 defence in the NFL, but that defence will be tested by San Diego's little tank, Darren Sproles. Sproles’ 328-yard game last week, plus his 139-combined-yard performance in the 2007 AFC Championship Game ranks him second all-time in combined yards (467) in a two-playoff-game span He can move into first in the category with 173 combined yards against Pittsburgh. However, the last time the two teams met, Pittsburgh won 11-10 as the Steelers Willie Parker rushed for 115 yards. 

Take Pittsburgh

Last week: 1-3

Season: 155-104-1
