The 49ers are rejuvenated thanks to Jimmy Garoppolo. But let's not go overboard here. San Francisco is 2-0 since Garoppolo became the starter beating the Bears and Texans. The Titans are a clear level higher than those teams if not two levels better.

The Titans are off a bad 12-7 road loss to Arizona this past Sunday. Before that, though, the Titans had won six of seven.

Tennessee's offense is capable of much better than it has shown lately. Marcus Mariotta has had some bad luck with interceptions. He remains an emerging franchise quarterback with two solid running backs. The Titans' defense is somewhat underrated having allowed 20 or fewer points in all but one of their last seven games.

The Titans are very much in the playoff picture holding down the No. 1 spot right now for an AFC wild-card berth. However, their last two regular season games are against the Rams and Jaguars. So they can't afford to lose this game. The Titans are putting tremendous effort and concentration into securing a win here. That's why the team has spent this week in California practicing on grass in warm weather after playing in Arizona this past Sunday.

The 49ers are improved due to Garoppolo. They still aren't a good team, though. Far from it. San Francisco doesn't usually play well either versus good teams going 5-15-1 ATS in their last 21 games against above .500 opponents. The 49ers have failed to cover in 10 of their last 13 home games, too.
