I thought the New York Giants were going to romp to victory Sunday night, but a funny thing happened: The Arizona Cardinals played strong defense and stopped them. The Cardinals? Defense? Say what you want about Eli Manning's throwing three interceptions, but the Cardinals had a lot to do with that by applying pressure on the quarterback and forcing mistakes. Fantasy owners seem to care so little about defense -- "reputation" has the Cardinals owned in only 10 percent of ESPN leagues and the hapless Tennessee Titans owned in 44 percent -- but the Cardinals are legit.
