Jacksonville Jaguars at New York Jets (+3.5, 39.5)

Jaguars' red-zone success vs. Jets' leaky downfield D

Two teams that outscored their opponents by a combined 51 points in Week 3 will lock horns this weekend as the New York Jets entertain Jacksonville. The Jaguars were the surprise of the weekend, rolling to a 44-7 throttling of the Baltimore Ravens in London, while the Jets stunned the football world by cruising to a 20-6 triumph over Miami. Jacksonville has the edge in this one according to oddsmakers, due at least in part to a sensational red-zone record through the first three weeks of the season.

Jacksonville came into the season facing serious question marks on offense, but quarterback Blake Bortles and rookie running back Leonard Fournette have put those concerns to rest - at least for now. The Jaguars come into Week 4 having scored touchdowns on two-thirds of their drives into the red-zone - putting them in the top third league-wide. Bortles already has six TD passes on the young season, while Fournette has three rushing scores to kick off his NFL career.

The Jets dominated play from start to finish against the Dolphins last week, surrendering only a last-second touchdown catch from DeVante Parker. But things haven't been so rosy overall, with New York surrendering touchdowns on 77.8 percent of opponent visits to the red zone. It's among the worst marks on the season, and represents a significant step back after the Jets allowed red-zone TDs on 56.9 percent of opponent red-zone trips in 2016.

Pittsburgh Steelers at Baltimore Ravens (+3, 43)

Steelers' second-half stinginess vs. Ravens' reeling offense

The Pittsburgh Steelers and Baltimore Ravens are both coming off stunning losses - and are looking for answers as they face off Sunday afternoon at M&T Bank Stadium. The Steelers lost a 23-17 overtime stunner to the Chicago Bears, while the Ravens were on the wrong end of a Jacksonville scoring spree overseas. This one is expected to be close - and that favors the Steelers, who have been one of the toughest teams to score against in the second half of games.

The Steelers were burned by a Jordan Howard rushing score in OT, but prior to that they had dominated teams after the half. Pittsburgh has allowed a paltry 17 points in the third and fourth quarters of their first three games of 2017, with the 5.7 second-half points per game against representing the third-lowest rate in the NFL. The Steelers have been even more impressive over the past two contests, allowing a combined six points in the third and fourth quarters against Minnesota and Chicago.

That bodes poorly for a Baltimore offense that has come out of the halftime break a slumbering mess to start the year. The Ravens have scored a combined 13 points in the second half of their first three games, with seven of those coming on a meaningless touchdown in the fourth quarter of the Jacksonville loss. Quarterback Joe Flacco has been the biggest culprit, amassing just 84 passing yards in the second half of two-plus games; he was pulled in London in favor of Ryan Mallett.

Tennessee Titans at Houston Texans (+1.5, 44)

Titans' elite pass protection vs. Texans' leaky O-line

The Tennessee Titans' offense has come alive after a slow start to the season, and Marcus Mariota and Co. will look to carry that momentum into Sunday's AFC South encounter with the Houston Texans. Tennessee has scored 70 combined points in victories over the Jaguars and Seattle Seahawks, and will look to tame another impressive defense on the strength of an offensive line that has managed to give Mariota all the time he needs to burn the opposition.

Tennessee boasted a top-12 pass protection unit last season, limiting foes to a 5.26 percent sack rate. Things have been a whole lot better through the first three weeks of the 2017 campaign, with Mariota going down on just 1.96 percent of dropbacks - the best rate in football. Blessed with more clean pockets than any starting quarterback in the NFL, Mariota has taken full advantage, completing 60 percent of his passes for 696 yards with three touchdown passes and just one interception.

Rookie Texans quarterback Deshaun Watson would probably give anything for protection like that. Unfortunately, he finds himself at the other end of the spectrum; Houston is surrendering sacks on a whopping 13.89 percent of dropbacks, the worst rate in the league. And while many of those sacks were allowed in a season-opening loss to the Jaguars, the five sacks allowed per game is still miles ahead of the 1.9 mark Houston posted a season ago.

Philadelphia Eagles at Los Angeles Chargers (-1, 47.5)

Eagles' elite time of possession vs. Chargers' TOP turmoil

With Chip Kelly at the helm, the Philadelphia Eagles were perennially one of the worst teams in the NFL in time of possession. But this is a new team - and with it, a new set of habits as the Eagles look to take charge of a competitive NFC East with a win over the host Chargers. Philadelphia is off to a sensational start on offense, and will look to control the play against a Chargers team that hasn't had the ball nearly as much as it would like through the first three weeks of 2017.

With top-10 rankings in both passing (252.7) and rushing yards per game (119.3), it's easy to see why the Eagles have been able to control the ball so effectively. Philadelphia's 34:12 time-of-possession average ranks 12 seconds ahead of the runner-up Carolina Panthers; that's nothing new to the Eagles, who led the league in that category a season ago after finishing dead last in each of the previous three seasons.

The Chargers finished with a modest edge in time of possession last season (30:21), but will be hard-pressed to match that success in 2017. Los Angeles comes into the week ranked among the league's bottom feeders at just 27:19 per game. After ranking 26th in rushing yards per game a season ago, the Chargers are 27th through three games - and at a woeful 30.3-percent conversion rate on third down, Los Angeles isn't extending drives, either. A similar effort Sunday could lead to a one-sided TOP result.
