Why the Buccaneers can cover the spread
Tampa Bay won two games in a row going into Week 14 but then fell at home to NFC South-leading New Orleans 28-14.
The Bucs actually drove the opening possession of the game 75 yards to a touchdown and led 14-3 well into the third quarter. But they gave up the last 25 points of the game and missed the cover as nine-point dogs.
Tampa Bay held a 20-19 edge in first downs, outrushed the Saints 105-100, held the high-powered New Orleans offense to just 298 total yards and won the turnover battle 2-1. But the Buccaneers also missed two field goals and had a punt blocked, all of which combined to cost them 13 points.
On the bright side, after struggling with turnovers all season long, Tampa Bay has turned it over just twice over its last three games while taking the ball away eight times.
Two weeks ago, the Bucs beat Carolina 24-17, and three weeks ago, they beat San Francisco 27-9. At 5-8 overall, Tampa Bay would like to win its last three games to finish at .500 for the season.
Why the Ravens can cover the spread
The Ravens won three games in a row into Week 14 but now look to bounce back from a tough 27-24 overtime loss at AFC West-leading Kansas City.
Baltimore spotted the Chiefs the first seven points of the game then used a 24-10 run spanning the halves to take a touchdown lead with four minutes left. Unfortunately, the Ravens gave up a 48-yard KC gain on a 4th-and-9, leading to the game-tying score, then lost it in OT.
Baltimore outrushed the Chiefs 198-94. The Ravens have now outgained three of their last four opponents and outrushed each of their last four foes.
The Ravens are also now 3-1 both SU and ATS since inserting Lamar Jackson as the starter at quarterback and are averaging 27 points per game.
At 7-6 overall, Baltimore still owns the No. 6 spot in the AFC playoff standings, despite not being listed among the top contenders on the latest AFC championship gambling lines at sportsbooks.
Smart betting pick
The Ravens are averaging 229 yards on the ground over their last four games, and their defense is almost 100 yards per game better than Tampa's. The smart money here bets Baltimore.
