The New York Giants and Arizona Cardinals open Week 4 with closely matched betting lines, with both Yahoo Sports articles reporting modest differences depending on how the matchup is listed. One listing has the Giants as slim home favorites, while another has the Cardinals opening as slight underdogs ahead of the game.

The outlets present the opening market from different perspectives—one focusing on the Giants’ advantage at home and the other framing the Cardinals’ position in the same matchup. The key common point is that neither team is a significant favorite in the early line, indicating a near-even market at the start of betting. Specific point totals or spreads are not detailed in the provided summaries, but both versions agree the contest begins with a small edge for one side and the other responding as the slight underdog.
