Whether you believe in the phenomenon or not, teams playing on their home fields do have an advantage over their opponents.
It could be something as small as the familiar bed that they get to sleep in or as large as the tens of thousands of fans who pack the stadium on a weekly basis to cheer their team to victory.
With every game left in the NFL regular season carrying more importance than ever before, even the slightest advantage is all teams need to raise their arms in a "V" when the final whistle blows.
Let's take a look at three teams that are so happy to be playing at home that not only is there a win coming their way, but a win that covers the point spread as well.

Tennessee Titans at Green Bay Packers (-12.5)
While Green Bay clinched the NFC North last week, head coach Mike McCarthy says that his team is not resting on its laurels heading into its Week 16 game against the Titans at Lambeau Field (h/t ESPN):
We want the bye week, make no bones about it. It's important to have a healthy football team, and if you have an opportunity to achieve the bye week, that's what we're working for.
I'm making it clear right now. We're going to play all the way through.
That’s bad news for a Titans defense that allows more than 28 points per game, the third-highest total in the league.
With Tennessee lacking a formidable pass rush, Rodgers will find himself with more time than he’s accustomed to. The reigning NFL MVP will have his way against an overmatched opponent.
Green Bay is going to make its head coach look like a liar, because McCarthy won’t be playing his starters all the way through. The team will get out to such a comfortable lead that the Packers can rest players in the fourth quarter.
Green Bay 37, Tennessee 14
New York Giants at Baltimore Ravens (+2.5)
There are a lot of teams in this situation that are very similar to us. They've got to win out to make it to the playoffs. Maybe they won't make it to the playoffs. We're in a good position and I think you have to be excited about this position.
While the Giants are talking the talk, walking the walk is a completely other thing altogether.
Baltimore is looking to avoid a four-game losing streak and clinch the AFC North with a win at home.
Look for the Ravens to put the ball in the hands of Ray Rice, both on runs between the tackles and in the passing game. New York's run defense has been mediocre at best, and its vaunted pass rush has been essentially non-existent.
Baltimore will find success against Big Blue, force Eli Manning to make mistakes and walk away with the victory.
Baltimore 27, New York 24
San Francisco 49ers at Seattle Seahawks (+1)
Seattle, in the midst of a three-game winning streak, has outscored opponents over the last two weeks by a combined score of 108-17 and has yet to lose at CenturyLink Field in 2012.
The continued development and maturation of Seahawks QB Russell Wilson has made this Seahawks team a far more dangerous one than the team San Francisco beat by a score of 13-6 in Week 7.
Seattle has the momentum and the home-field advantage—the Seahawks will pull off the upset and stay alive for the NFC West title.
Seattle 21, San Francisco 17
