The Niners are going to be UP for this game.
Part of the reason they've been winning (outside of the superb play by Garapolo) is that except for pride, the games are meaningless, so they can just let it all hang out, take some risks, and play relaxed.
The Niners were being embarrassed in battling the Browns for the worst record.
Suddenly with a good QB, everything changes and they now feel they can win and end the year on a high note. Heck, Hyde actually had the gall to say that the Niners are going to win the Superbowl at the end of next season. I'll bet his feelings mirror many on the squad.

It's a lot easier to play loose when you are fighting for nothing more than pride and newfound enjoyment of playing the game. What's there to lose for the Niners? They'd like nothing better than to come into LA in their last game of the year before they go on vacation and knock off the Division Champs.

THIS is the trap game everyone has talked about before. No amount of McVay speeches is going to make the Rams players get their juices flowing for this game. They all know this is about what happens 2 weeks from now.

THIS is the game that your number one concern MUST BE player health.
