Ironically, it hasn't been the defense that has cost us the 7 niners games. There were a couple of times the defense let us down, the most memorable one is the second 2019 contest when they allowed Garopolo to convert two 3rd and 16's on the final drive. That was Wade Phillips defense and probably the game that cost him his job. The other was week 17 last year when they allowed SF to march down in 1:27 to score the tying TD. But the offense has scored more than 20 just twice and were limited to 7, 16, 10 and 9 four other times. Plus we've had pick sixes in 4 of the last 6 regular season games vs SF. For the most part, when Sean McVay's Rams screw up any game (be it vs SF or anybody else), it's overwhelmingly because of the offense.
