Why the Redskins can cover the spread

Washington kept its playoff hopes alive with a come-from-behind 16-13 victory at Jacksonville last week. The Redskins trailed the Jaguars 13-6 in the fourth quarter but drove 68 yards to a tying touchdown, got the ball back with an interception, then made two first downs and kicked a game-winning field goal at the buzzer for the outright win as seven-point dogs.

For the day, Washington held a 16-11 edge in first downs, a 33-27 edge in time of possession and won the turnover battle 2-0, creating a plus-3 points differential.

Journeyman quarterback Josh Johnson, making his first start for his new team, hit on 16 of 25 throws for 151 yards and a touchdown, without a pick, and ran the ball for 49 yards. Meanwhile, the Redskins defense held Jacksonville out of the end zone all day; the Jags' only touchdown came on a punt return in the second quarter.

Washington is now 4-3 both SU and ATS on the road this season. At 7-7 overall the Redskins trail Minnesota by just a half-game in the battle for the second NFC wild-card slot.

Why the Titans can cover the spread

Tennessee stayed alive in the AFC playoff race with a 17-0 blanking of the Giants in the rain in New Jersey last week. The Titans drove their second possession of the game 75 yards to a touchdown and the defense did the rest, on the way toward the cover as 2.5-point favorites.

For the day, Tennessee out-rushed New York 215-47, as Derrick Henry rumbled for 170 yards on 33 carries while the Giants' Saquon Barkley managed just 31 yards on 14 lugs. The Titans also ground out a 35/25 advantage in time of possession and won the turnover battle 2-0, creating a plus-10 points differential.

Tennessee has now out-gained its last three opponents by 112 yards per game, going 3-0 SU and 2-1 ATS at sports betting sites in the process.

At 8-6 overall, the Titans trail Baltimore and Indianapolis by tie-breakers in the battle for the second AFC wild-card spot.

Smart betting pick

Tennessee owns the better running game and the better defense. Washington, meanwhile, managed one touchdown last week, two garbage-time touchdowns two weeks ago and one fluky touchdown three weeks ago. Double digits can be hard to cover in the NFL but smart money here gives the points.
