Home-field advantage in sports is often the difference between winning and losing.
Players on the home team feed off the energy of the crowd, and opposing teams struggle to communicate over the roaring thunder.
Visiting teams that can shut up a raucous mob take extra satisfaction in their work.
Winning games on the road in the NFL isn't easy, but there are a few road warriors destined to win in Week 4.
Indianapolis Colts at Jacksonville Jaguars
If ever there was a gimme, then this is it.
The Colts went into Candlestick Park in Week 3 and knocked off the NFC champion San Francisco 49ers by bullying them into submission.
Indy dominated the line of scrimmage on both sides of the ball, forcing San Francisco to react rather than impose its will on the Colts, as is usually the case.
The Colts are becoming a true threat in the AFC, but the same can't be said for the Jaguars.
In fact, Jacksonville will be lucky to win two games this year, thanks to one of the least talented rosters in the league.
The Oakland Raiders dominated the Jaguars in Week 2.
Arizona Cardinals at Tampa Bay Buccaneers
Arizona is struggling on both sides of the ball in Bruce Arians' first season at the helm.
Thankfully, a trip to Florida should help this team get its sea legs back under it, as the Buccaneers appear ready to implode in Greg Schiano's second season.
Josh Freeman has been atrocious this year, and he deserved to get benched—which he did, as noted by Jim Corbett of USA Today Sports. In Freeman's place is rookie Mike Glennon, who was equally as bad when he got a chance to play in the preseason.
To add insult to injury, top receivers Vincent Jackson and Mike Williams both missed practice with injuries this week, as noted by Joe Smith of the Tampa Bay Times.
Tampa Bay's offense is a mess, and the Cardinals will have no trouble exploiting this weakened team in Week 4.
Dallas Cowboys at San Diego Chargers
Philip Rivers has been revitalized this season under new offensive coordinator Ken Whisenhunt. He's thrown eight touchdowns and just one interception—a winning formula most of the time.
Unfortunately, San Diego's defense is incapable of stopping opposing offenses from making plays at will deep down the field. The Chargers feature the league's last-ranked passing defense, allowing 341 yards per game.
This is bad, bad news when considering the Dallas Cowboys are coming to town in Week 4.
Dallas has two excellent receivers in Dez Bryant and Miles Austin, and it features a future Hall of Famer in tight end Jason Witten. Tony Romo has been playing much better this season than he did last year, completing 72.2 percent of his passes with six touchdowns and just one interception.
And running back DeMarco Murray really got things going on the ground last weekend, rushing for 175 yards.
San Diego's talent-poor defense will be overwhelmed by Dallas' impressive offense, and the Cowboys will roll.
