Last week’s wild card playoff games were wild to say the least. Some teams underperformed and other stepped up big (cough Broncos cough). This week will feature four incredible games with no guarantees. Below are previews for each of the divisional week playoff games.

New Orleans Saints at San Francisco 49ers
This is one great matchup. After defeating the Detroit Lions by 17 points last week, the New Orleans Saints will travel to face the San Francisco 49ers. The Saints, led by star quarterback Drew Brees, have the highest scoring offense in football, but will have their hands full in Candlestick. The Niners defense won’t make things easy as it was one of the best all year and the best at defending the run, giving up just one rushing touchdown all year. A New Orleans victory hangs on its offensive production. If the Saints offense continues to click and Brees has two or more touchdowns and no more than one interception, and the running game can average at least four yards per game, the Saints are heavy 82 percent favorites. On the other hand, the 49ers will win if their defense and running game steps up. If the Niners can get two or more interceptions and Frank Gore averages at least 4.5 yards per carry, they have a 58 percent chance of winning.

Denver Broncos at New England Patriots
This Saturday will be Tim Tebow versus Tom Brady, round two. Brady won the first matchup as the Patriots won 41-23 in Mile High Stadium. Last week the Denver Broncos defeated the Pittsburgh Steelers with an overtime 80-yard touchdown pass from Tebow to Demaryius Thomas. Tebow will look to continue his magic in New England, but it will be tougher this weekend. Coach Bill Belichick won’t make the mistakes the Steelers did, and Brady is much more dangerous than a hobbled Ben Roethlisberger. If Brady and the Patriots offense have a normal passing day with 300 or more passing yards, three or more touchdowns, and no more than one interception, the Patriots are overwhelming 94 percent favorites. The Broncos will have to have a better than normal day to beat the Pats. Denver is a 52 percent favorite if Tebow rushing for 50 or more yards and one or more touchdowns, Brady throws at least one pick, and Thomas has over 100 yards receiving and one or more receiving touchdowns.

Houston Texans at Baltimore Ravens
The Texans captured their first ever playoff victory last week over the Cincinnati Bengals. Houston dominated, walking away with a 31-10 win. The Texans and the Baltimore Ravens played once during the regular season. Baltimore won at home 29-14 by holding Houston’s running game to just 93 total rushing yards. The Texans’ chances don’t look good, but improve significantly if they get good production from running back Arian Foster and wide receiver Andre Johnson. If Foster rushes for more than 50 yards and Johnson scores at least once they have a 50-50 shot of winning the game. The Ravens also need a solid running game to be victorious. If Ray Rice rushes for 100 yards or more Baltimore is a heavy favorite at 88 percent. However, if Rice rushes for less than 100 yards and quarterback Joe Flacco is sacked three or more times and turns the ball over at least once, the Texans are 57 percent favorites.

New York Giants at Green Bay Packers
The New York Giants seem to be the hottest team in the NFL. They won their way into the playoffs by defeating the Dallas Cowboys in week 17, and easily dispatched the Atlanta Falcons last week to move on to face the Green Bay Packers. The Packers haven’t played in two weeks thanks to their well-deserved bye after an incredible 15-1 season. Analysts on ESPN have been talking up the Giants because of their recent success, but they remain eight point underdogs and have only a 25.8 percent chance of winning the game. New York’s chances get much better if they dominate on the ground. If Ahmad Bradshaw and Brandon Jacobs each rush for more than 50 yards, the Giants have a 59 percent chance of victory. However, if they each have fewer than 50 yards their chances plummet to 17 percent. The Packers will win if Aaron Rodgers continues to be Aaron Rodgers. If he throws for his projected 300 yards, three touchdowns, and fewer than two interceptions the Packers are 82 percent favorites. If Rodgers uncharacteristically throws more than two picks and Eli Manning throws less than one, the Giants gain the edge at 52 percent favorites.
