This was a comfortable win on the road by the 49ers this year, but it wasn't the offense that shined. It was how strong the defense played throughout the game.
The Titans were completely frustrated when they were unable to move the ball past the 49ers 45-yard line in the first half. Their sequence of offensive drives for the first half resulted in three punts, one interception and the end of the second quarter.
Tramaine Brock's interception was one of the most important plays of the game as the 49ers didn't pull away until later. The Titans defense kept Tennessee in the game at 10-0, but the offense of the 49ers clicked after Brock's turnover. This was backbreaking for the Titans as Jake Locker threw his first interception of the year.
Like the last two weeks, the 49ers offense had another short field to work with as they started the ball on the Titans' 45-yard line. Colin Kaepernick was able to establish a rhythm when he scrambles for 20 yards and found Vance McDonald on a 21-yard pass two plays later. The short field kept the momentum on the 49ers' side and they never had to look back.
The offense stayed with their identity to start the second half with a 12-play touchdown drive that took 7:40 off the clock to start the third quarter. By that time, the defense was well rested and the Titans were shutout for three quarters. Pass coverage stayed strong and Justin Smith was a force in the pass rushing attack.
With the Titans unable to generate any momentum outside of a few first downs in the opening half, the 49ers defense locked down the entire game until it was garbage time allowing a few late points.
While playing through a groin injury, Patrick Willis had the type of game he needed after saying there are no excuses to blame an injury for not playing as well. Willis was covering Delanie Walker in coverage but did great at stopping the run when the 49ers needed to.
Chris Johnson was held to only 39 yards on nine carries as the Titans were forced to throw the ball more while trailing.
When the fourth quarter came around, it began to look like a 49ers home game with all Titans fans heading towards the exit. Chants in favor of the 49ers were breaking out with everything going San Francisco's way. It was an exceptional performance by the defense as they have been consistent all season long.
