Remember the days of "same old Rams?" They're over now and sooner than the 49ers would have liked.
The Rams were the NFL's most pathetic franchise in 2009 and were therefore awarded the top picks in last April's draft.
They did not exactly become a powerhouse overnight, but they have already quadrupled their wins from last season.
The youth they've brought in over the last couple years is apparently not a joke, and they've making as good of a playoff push as any team in the NFC West.
Ladies and gentlemen, this is a rivalry that predates 49ers glory. These are the only two remaining teams of the old NFC West and neither has been afraid to kick the other when they're down.
