From what I say Murray hasn't improved, i.e. progressed in his development. He's still a two read and scramble QB who still will force passes. The Cards won as much as the Niners gave the game away with stupid mistakes.
My biggest impression is that once again I say that Jimmy G still is a very long way from being an elite QB. He still throws bad passes and his ball placement is really inconsistent. The Niners had problems in coverage so I can see how the Rams with their elite 3 deep receivers and very good TE will really give them problems. As I thought before the season, that the Niner's pass rush doesn't look nearly as imposing as last year. They really miss Buckner inside. They have one RB who is lightning fast with good hands as a receiver. But the Rams have the secondary IMO to outclass their receivers.
I think the Rams match up well to both these teams. If the Rams come out hot tonight I think the Rams will win the division.
