Week 15 means it's clearly crunch-time for all NFL teams, and like every week there will be upsets this Sunday. Here are three underdog teams sure to pull off their own upsets in one of the last weeks of the regular season.
San Francisco 49ers
Sure, head coach Jim Harbaugh's team is playing the Patriots; that'll just make the victory that much sweeter.
New England will be at home in Foxboro and are riding a seven-game winning streak, but the 49ers have what it takes to win this Sunday Night Football battle.
San Francisco has knocked off some of the NFC's best teams in 2012, like Seattle, Minnesota, Green Bay and Chicago. One of the reasons this team has been able to win those crucial games is through its No. 2 ranked passing and rushing defense.
There's no denying just how explosive the Patriots can be on offense with Wes Welker, Tom Brady and co., but they're not unstoppable. New England struggled to get on track offensively against Seattle earlier this season and that same approach is likely what San Francisco will try to implement.
The 49ers will take a cue from their NFC West rivals and get into Brady's head while surprising the Patriots defense with new starting quarterback Colin Kaepernick.
The Cowboys will face their long-time cross-conference rival in Pittsburgh and will lock up a key victory at home in the process.
Dallas has so far proven its recent history wrong with two victories this December in the regular season. When you consider the team's comeback victories against Cincinnati and Cleveland in recent weeks, the 'Boys have proven formidable.
The Steelers will be starting Ben Roethlisberger at quarterback for just the second time in a month. While Big Ben is as gritty a veteran as you'll find in the NFL, he showed some rust in his game in Week 14.
Against the Chargers, Roethlisberger completed barely over half his passes and threw an interception. It's clear he's still getting back into his rhythm, which the Cowboys will capitalize on in this contest.
Ultimately, Big Ben's struggles will be the downfall of his team and the Cowboys will defend their home turf down in Arlington in Week 15.
New Orleans Saints
The Saints have obviously had a miserable go of things this season but they'll at least be smiling after playing spoiler to division rival Tampa Bay.
In Week 15, the Buccaneers became the first team to lose to the Philadelphia Eagles in eight weeks. The Saints couldn't have picked a better week to play against this young squad that is likely rattled after that disappointing defeat.
New Orleans still owns the NFL's No. 2 passing attack lead by none other than Drew Brees. While it's been proven he can't win the game for the Saints on his own this season, he should post a good day against the Bucs passing D that ranks dead last in the league.
Brees can't win every game for the Saints on his own, but he should be able to win this one for his team pretty much single-handedly.
