The Rams shit the bed, plain and simple. I don't think anyone but the SF faithful expected the 49ers to put up that kind of fight, but the Rams had plenty of opportunities. Yet another blocked kick, a missed kick, a goal line fumble, a muffed kickoff to start OT, and a 4th and 1 call with the game on the line that a six year old would have been prepared for.
I really thought McVay would have at least drawn up a QB option or outside zone and was honestly half expecting another one of the one-step-drop quick screens to Nacua where Adams takes both defenders with him for a couple steps to let Nacua cut underneath...it seemed to be working well earlier in the game.
When you can look at both of their losses and say they very well could have been wins if the field goal team had been perfect I think you need to change something there for sure. The big guys up front aren't giving Karty enough time, or Karty needs to get the ball up faster, or both. I don't remember if it was an earlier field goal or one of the extra point attempts, but there was another kick that ended up being good that looked like Karty kicked it directly over or under a diving 49er...he was there, he just didn't get a hand on the ball.
