The St. Louis Rams had 10 days to mull over a dispiriting blowout loss to the San Francisco 49ers, the third straight time they were so far behind there was no coming back. Sure, it was winless Jacksonville on the other side of the ball. At this point, it didn't matter. "It just takes a snowflake to start an avalanche," said safety Matt Giordano. His 82-yard interception return for a touchdown was one of several big plays from the defense in a 34-20 victory over the Jaguars on Sunday that ended a three-game losing streak.
