Fisher's teams had good players in a number of spots. But, they just couldn't seem to put it all together and so they would play really good teams pretty tough, but still manage to lose.
The Niners have a far better offense than the Fisher Rams ever dreamed of. And even with good talent in a number of spots, they're the "almost" team.
Yeah, the Rams won a lop sided game. And yet, if you watch the LOS the Niners did a good job on Offense run blocking, and on Defense constantly put pressure on Goff and did a pretty good job on the run game as well.
