Overall the 49ers vastly outplayed them. Two of the Titans TDs came in the 4th quarter when the game was pretty much in hand and one of them came off really good field position due to a strip sack fumble but they aren't going to put up 37 points against good teams in the playoffs. They do need something from the defense and good QBs and play callers are going to pick them apart with no pass rush. It will be interesting to see if they get more aggressive. They tried that against Stafford the second time they played and he torched them. They aren't really built to be a high blitzing team. I think they will have to pick their spots, disguise them well and be very creative.
