Ravens (3-2) at Titans (3-2)

Danny Sheridan’s line: Ravens by 1

Ravens’ keys to victory: Protecting QB Joe Flacco will be paramount. When he has time, Flacco can make the right moves in the pocket and get the ball to playmakers such as WR John Brown, and he has a lot of targets — in the Week 5 loss at Cleveland, he completed at least four passes to four receivers. Brown has been a revelation in his first year in Baltimore, catching at least three passes in every game and scoring three touchdowns.

Titans’ keys to victory: Their offense should attack the middle of the field, which the Ravens have struggled to defend. QB Marcus Mariota doesn’t throw for a lot of yards — he has had more than 129 yards passing just once in four games this season — but he’s also lethal running the ball. Getting pressure on Ravens QB Joe Flacco early will be important. The Titans wouldn’t mind an easy victory for a change; all five of their games have been decided by seven points or fewer, and four of them have been decided by one to three points. Their 13-12 loss at Buffalo in Week 5 came after three consecutive three-point victories.

Matchup to watch: Ravens WR John Brown vs. Titans CB Malcolm Butler. Butler has struggled this year, but if he’s able to shut down Brown one-on-one the Titans could limit the Ravens’ solid passing attack. Flacco threw the ball 56 times at Cleveland.

Who wins? These teams don’t play often — this is only their fourth meeting this decade — and the Titans scored a 23-20 victory last year at home. Same site, same result.

Titans, 23-20
