Baltimore Sun columnist Mike Preston picks three key matchups in the Ravens' game against the Arizona Cardinals.
Cardinals WR Larry Fitzgerald vs. Ravens CB Jimmy Smith: Fitzgerald is off to one of the best starts of his career. In six games, he has 43 receptions for 583 yards and six touchdowns, including three in Week 2 against the Chicago Bears. Smith had a slow start, but has been consistent the past three games. He appears to be playing with more confidence. Smith is third on the team with 31 tackles and has two interceptions.
