The Arizona Cardinals opened as a 2.5-point favorite against the Seahawks for their Week 1 game, but the line has switched by five points — the most of any other Week 1 line — and Seattle is now favored in the game. The Seahawks are favored by 2.5 points most sports books, and favored by 2 points at other places. The line change can be attributed to factors related to each team.
Arizona has gone 1-3 in four preseason games, and their first-team offense has been unimpressive. Kevin Kolb and John Skelton are competing for the starting quarterback job and neither player has fared well. Their offensive line also seems porous, which is not making the job of the quarterbacks any easier.
Seattle has gone 3-0 in the preseason and looked impressive scoring 101 points. Third-round draft pick Russell Wilson (pictured) has played brilliantly and was named the starting quarterback after going 35-of-52 (67.3%) for 464 yards, five touchdowns, and one interception. He’s also run for 150 yards and a touchdown and appears to be a dynamic playmaker.
Bettors are so high on Seattle and down on Arizona that they’ve flipped the line five points. Arizona (8-8) actually finished a game better than Seattle last season, but the sports books still thought Seattle was the better team entering this season. We know that based on the opening line that favored Arizona by 2.5 points; home field advantage is worth at least three points in NFL games.
