The Cardinals are easily the most underrated 3-0 team in the NFL. Sure, they haven’t really played any tough opponents in the Saints, Bears and 49ers, but good teams win games they are supposed to win. Arizona has done that with ease, blowing out San Francisco last week and doing the same to Chicago on the road the week before. People underestimate how much Carson Palmer means to this team. The Cardinals have won 16 of the last 18 games he has started. Are the Rams — a team that lost at home to the Steelers last weekend after Ben Roethlisberger left with an injury — going to stop him from making it 17 out of 19? I doubt it, and 6.5 points doesn’t sound like much to lay.
