The Rams got away with one dirty hit by Ben S. The Niners got away with a few and got called for a few which evens it out some. Warners hit was disgusting from behind and he had to leap to hit him with the crown of his helmet. Ward should have been tossed out for his dirty play. They pulled Ramsey down by his facemask.
Either way, the officials had nothing to do with the outcome of this game. The Rams out hit, outmuscled the Niners, and beat them at their own game.
Clean (as far as controversy) goes and a really great win.
