Week 4 NFL Lines See Ravens as Heavy Favorites Despite Some AdversityThe real referees are back, and with their return, comes even more excitement for Week 4 of the NFL season.

With that in mind, let's get right into this week's lines, courtesy of Bovada.lv.

Cleveland at Baltimore (-13)

The Ravens are about to play their fourth game in 17 days on Thursday night, which is absurd. They're coming off of a Sunday night slugfest with the Patriots. Yet, they're almost a two-touchdown favorite against the Browns.

New England (-4.5) at Buffalo

The Patriots hope to bounce back after losing to the Ravens on Sunday night, while the Bills have something to prove coming off a pair of wins against a couple of weaker clubs (Kansas City, Cleveland).

Minnesota at Detroit*

It's tough to get a grip on either of these NFC North teams, and they'll meet this weekend in what's actually a pretty important game between division foes.

Carolina at Atlanta (-7.5)

The Falcons — 3-0 against the spread this year — are 7.5-point favorites in their latest attempt to prove that they are the best team in the NFL right now.

San Francisco (-4.5) at New York Jets

The 49ers are giving 4.5 points coming off their first loss and they're playing the dreaded "West Coast team kicks off at 1 p.m." game. 

San Diego (-1) at Kansas City

The Chargers got throttled last week by the Falcons, but they're the slightest of favorites on Sunday against the Chiefs.

Tennessee at Houston (-12)

Houston also has an argument as the league's best team, and they're a 12-point favorite at home this week against the Titans, who are coming off their first win of the season last week against the Lions.

Seattle (-3) at St. Louis

The Seahawks got lucky last week; they are three-point favorites against the Rams this week.

Miami at Arizona*

The Dolphins gave the Jets all they could handle a week after knocking off the Raiders, but they'll get a tough test this weekend against one of the league's biggest surprise teams.

Cincinnati (-3) at Jacksonville

This will be an entertaining football game.

New Orleans at Green Bay (-8)

Two desperate teams square off in Green Bay with the Packers giving eight points after coming up short in the last time we'll see the replacement referees.

Washington at Tampa Bay (-3)

The Bucs host the Redskins, who are underdogs again after dropping one to the Bengals last week.

New York Giants at Philadelphia (-1)

The Giants rolled on Thursday night in Carolina, yet they're a one-point underdog against the Eagles, who got rolled by the Cardinals in the desert last week.

Chicago at Dallas (-3.5)

The Cowboys beat Tampa Bay last weekend, and they're 3.5-point favorites in the Jerry Dome on Monday night against the Bears.
