With three impressive wins under their belt, the Arizona Cardinals are betting favorites for the first time this season. Arizona opened as a 4½-point favorite for its game against the Miami Dolphins on Sunday.

The Cardinals have been underdogs in all three games this season, including last week when they were 3-point underdogs to Philadelphia. Arizona is 3-0 against the spread this season and 10-3 against the spread in its last 13 games dating back to last season. Since opening as a 4½-point favorite, the odds have moved even further in Arizona's direction. The Cardinals are as high as a 7-point favorite, according to Odds Shark.

The Dolphins are 1-2 this season and are also 1-2 against the spread. Miami's only cover came in Week 2 when they beat the Oakland Raiders despite being 1½-point underdogs. While they are just 1-2 this season, the Dolphins are 10-3 against the spread in their last 13 regular-season games.

The total for Sunday's game opened at 41, a number history tells us might be too low. The total has gone over in four of the last six meetings between the teams. Miami games have also been prone to going over recently, including four of the last six.
